You may need to use another translator, or sometimes I have to use proxy to view that Russia site.

As for BIOS edited, you can save AMIBCP, or edit from IFR variables either in grub or directly in the BIOS module you extract to get IFR (via hex), then put back into BIOS same way you extracted and flash it.
I think disable PCIE is possible, if you need me to look at that and figure out what all you need to set (Or do it for you) let me know. I would not do this without programmer in hand in case you loose display for all internal and external connections

They removed the name there, it's not really blank. I was only guessing that may be the one, as for the rest of your questions there I do not know. << Talking about the FormId: 0x2712 reply

Both Advanced have labels in the BIOS, so nothing you see in AMIBCP correlates to that in IFR, at least not in the way you mentioned I think. The blank/no name folder in AMIBCP when present is a debug folder

This is not valid, and may be working now due to being invalid >>
0x4CB53 Suppress If {0A 82}
0x4CB55 False {47 08 4A 0D 01 00 FF FF} << ? False is only two bytes 47 02 (or other values depending on BIOS in question), and if you cut that Question ID {14 08 4A 0D 01 00 FF FF} out with less bytes then it breaks the IFR output, better to do as below

If you want to remove that suppress/gray out if, do like this. Delete 29 02 x 2 after {0F 0F 02 00 02 00 29 0D 00 00 FF FF 00 12 27}, and place 29 02 in front of {0F 0F 02 00 02 00 29 0D 00 00 FF FF 00 12 27} instead. Then IFR will show as below, nothing grayed out or suppressed
0x4CB53 Suppress If {0A 82}
0x4CB55 QuestionId: 0xD4A equals value in list (0xFFFF) {14 08 4A 0D 01 00 FF FF}
0x4CB5D Gray Out If {19 82}
0x4CB5F QuestionId: 0xD42 equals value 0x1 {12 06 42 0D 01 00}
0x4CB74 End If {29 02}
0x4CB76 End If {29 02}

Did you flash this mod? Does it show in BIOS, and are the items working?

Good news, I finally tweaked bios menu to get all hidden sections :)

That was really not a easy task, kind of exhausting and seriously didn't think i will make it right haha
Tried many things like replacing a reference from IFR to get another but realized it was still pointing to the old one.
Also the advanced menu do not include chipset menu found in the Setup/Main section ...

So I decided to make advanced menu appear and replace a section in it with chipset menu.
The result now is the advanced menu shown with a more proper way i think :) (tried moving the ref out of the suppress condition but it does not show the menu in the bios that way)

0x4CB53 Suppress If {0A 82}
0x4CB55 QuestionId: 0xD42 equals value in list (0x1) {14 08 42 0D 01 00 01 00}
0x4CB5D Gray Out If {19 82}
0x4CB5F QuestionId: 0xD42 equals value 0x1 {12 06 42 0D 01 00}
0x4CB65 Ref: Advanced, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0xD29, FormId: 0x2712 {0F 0F 1E 00 02 00 29 0D 00 00 FF FF 00 12 27}
0x4CB74 End If {29 02}
0x4CB76 End If {29 02}

I took a variable that I know is true for the questionId (0xD42 refers to the access level as an administrator which is the default one even after a CMOS reset) and filled the list with 0x1 ( I think that it just test if the value of the variable is the same as one in the list :) )

After that I decided to add the chipset menu so I followed the tutorial in the link you gave me from overclockers.ru (what was showing me a blank page is my adblocker ... lol ) and there comes the AMITSESetupData editing ...
This part was really tedious because it involve looking at Hex ... finding etc ... but the tutorial is pretty well done even with google traduction.
So I changed the destination ID from SDIO Configuration in advanced menu (this one didn't work and hangthe bios anyway ...) to Chipset form.

And also changed the reference in IFR :
0x28617 Ref: SDIO Configuration, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x29, FormId: 0x27E5 {0F 0F 43 16 44 16 29 00 00 00 FF FF 00 E5 27}
TO
0x28617 Ref: Chipset, VarStoreInfo (VarOffset/VarName): 0xFFFF, VarStore: 0x0, QuestionId: 0x29, FormId: 0x2713 {0F 0F 1F 00 02 00 29 00 00 00 FF FF 00 13 27}

Tested the modification and all work fine so far. THere are so many sections in the bios that i didn't tested all and maybe some can cause a freeze that need shutdown and restart with power button ... ( I don't mean changing value but just entering the menu)

While exploring available options I found a way to disable the PCIE port from the dedicated GPU under chipset / System Agent (SA) Configuration / PEG Port configuration and it works fine.

Honestly I don't think I could have made it without your help and Mov AX _ 0xDEAD for his tutorial.

Still AMIBCP do not show the move of chipset menu but i think this is because I didn't changed enough values (like the parentID in the chipset reference ...)

Wow, great work @Lugburz - I mod BIOS all day long and could not follow along there, but maybe I was tired the day I first looked into that, need to try again I suppose
Thanks @Mov AX, 0xDEAD for the guide, it's been helping, I saw another user on another thread have some success too!

@Lugburz Hey i'm trying to modified my FX504GE BIOS (i7-8750H , GTX1050Ti Model) , i able to flash my modified bios by using AFUWINx64 with /GAN command..
But.. the problem is i can't see the hidden "advanced menu" in my bios...
Can you explain more details how you made it?
Sorry for my english.
BIOS Version 315

But, can you verify your flash with AFUWINx64 /GAN is actually flashing in, or only looks like it flashes (This happens a lot). Flash back to older version, check BIOS version in BIOS, then flash back to latest version and check again.
Did BIOS version change each time? If yes, then your /GAN flash is working, if not, then it's not and only looks like it's working.

Ok , i already verified the bios is still same means the modified bios is not flashed by afuwinx64 with /GAN Command

You will have to flash using FPT, I suggest you make a backup of the BIOS region with FPT first (FPTw -bios -d biosreg.bin), then edit that, then flashback with >> FPTw -bios -f modbiosreg.bin
You will have to first get correct ME System Tools package matching your ME version from here - Intel Management Engine: Drivers, Firmware & System Tools

Then follow this guide to unlock your BIOS Lock/SMI Lock
[GUIDE] Grub Fix Intel FPT Error 368 - BIOS Lock Asus/Other Mod BIOS Flash

Then you can flash using the above flash command.

@Lugburz Hello, I want to ask, have you found the reason for the low frequency of the computer CPU clocks? And how can you do it to refresh any BIOS file? Can you elaborate? Because I am also a newbie, the posts you sent, I see it complicated.Thanks

@guangzhishun - is that low CPU speed at idle too, or only under load? If under load, it may be due to temps/overall heat or TDP limits.
You do have Speedstep, EIST, C1E disabled right?

only under load.However, it is not because the CPU temperature is too high, the frequency is low. because the temperature is only 60 degrees.

Limit could be set at 60c? More likely TDP setting or power limit setting
Wait and see if @Lugburz has any input, maybe he has same CPU as you (post your CPU so you two can compare CPU/Temps etc when he replies)

Sorry for the wait :/

@wilson98 : I started trying to flash with AFU before knowing there is another way and limitations. Saw somewhere (maybe this forum) that AFU with /GAN command available is an old version and will probably not work with Aptio V bioses. In fact, I tried it and it never worked even with the latest version (with another command). It just does not flash anything or freeze after reading the file ... You have to use Intel programming tool (as Lost_N_BIOS said ). Should be the latest (for CSME 12). Not sure at 100% because we don't have the same laptop

@guangzhishun : mine is shipped with I5 8300H, does not have any sort of frequency lock (non turbo frequency at 2,3ghz, turbo frequency up to 4ghz, verfied and working as it should). I suppose you have the laptop shipped with an I7, and I saw some ppl complaining about this "issue".
Maybe have a look first with Intel Extreme tuning Utility and check frequencies under load, also CPU core multiplier, reference clock, maybe Turbo boost Power too and compare with what it should be from the official specifications of your CPU ...

Ok, thank you for your advice. In fact, my CPU is also i5-8300H, but I have never seen it turbo up to 4ghz

It greatly depends on the work asked to the CPU.
You should try to monitor frequency with some stress test or benchmarking tool and see if it goes up near 4ghz
CPU have some integrated "things" to optimize power based on load like P-states or speedshift for example.
Not a expert in this but i mostly do some research before tweaking the bios to understand what I do and discover all sort of things like this :)

My i7 cpu clock also down to 2Ghz when start running my GPU , i already tried use intel xtu to set it but still down to 2Ghz when gaming
