Great to hear it, thanks for quick report back! On the fans, you have to enable or disable one of those overall thermal control things before the trip points work (either DPTF or the other one, you can only use one type at a time). Probably one you are adjusting isn't the one enabled, or you tried to enable both methods.
I checked, default one enabled is the ones at Thermal >> Platform Config. However, in DPTF >> Policy Config There is policy set for both active and passive, you may need to disable.
But all this is guesses based on looking at settings and the help comments/info, I've never used any of that, only helped others to adjust/use when asked - and yes, it's often tricky, but you will figure it out.

Is your ME FW working, do you see ME FW version in Main BIOS page or with HWINFO64, or does it show N/A or 0.0.0.0? If NA or 0.0.0.0 then ME FW is messed up, and that needs fixed, this can cause fan detection errors. Did the fan speeds show before?

No, there is no type of fan control in these kind of BIOS, only those trip points. It should kick in way before 95C!! Something wrong with settings probably. Did it do that on stock BIOS settings too, or only after you tried adjusting stuff? Did you load optimal defaults first?
95C is the passive trip point, but all the others there should be kicking in before that. As simple test, you could enable Automatic Thermal Reporting, that would automatically adjust things (ignoring all those other settings).
If that works, then disable again, and adjust settings more until you figure it out, but always start by first loading optimal (restore defaults) from the save and exit page

I have disabled DPTF AND automatic thermal reporting then I tried changing the trip points and fan rpm ,it dint worked.Further I tried with automatic thermal reporting enabled and then the fan kicks in at 85,irrespective of the trip point settings.For the last method I disabled Automating thermal reporting and enabled DPTF.Inside the DPTF I have lowered the active trip point and no luck .

SO if both DPTF and automatic thermal reporting are disabled , the fan kicks at 95 (irrespective of trip points and fan speed settings)
If DPTF or automatic thermal reporting are enabled the fan kicks in around 85-90 (irrespective of active trip points)
The stock bios behaves the same ,because in stock bios both of this settings were disabled so the fan kicks in at 95. No issues with the ME version ,it shows up in the bios.The fan speed dint showed up in the applications but inside the bios it shows up(stock bios also had the same issue).

It may be controlled by EC FW, but I have my doubts on that since by default DPTF was disabled and the other method was enabled. I'd imagine both of those would be disabled if it was EC controlled only.
So, even at stock BIOS, before you use any mod BIOS, the fans weren't working properly and only turn on at 95C? If yes, something is wrong, you maybe should ask Asus about that in a direct email, especially if you are under warranty.
Put new thermal paste on the CPU and GPU, this may be the real issue, maybe fans runs but aren't loud enough for you to hear until it gets super hot and then they go 100%

The help you need setting and understanding these things is not something I know how to advise about.
Something like that you'd have best luck asking for help at notebookreview forum probably, I'd say ask in Asus forums too but they'd assume you have locked BIOS and it should all be working fine.

For your consideration ,both Automatic thermal reporting and DPTF were disabled in stock bios.So I think the fans are controlled by EC FW,If that is the case then is there anyway I could try to change those settings?

Ahh, yes, I see now, sorry I thought the one at CPU Thermal config was enabled, I checked and see as you mention both are disabled.
The CPU thermal config one (DTS SMM), the help files says this -
Disabled: ACPI thermal management uses EC reported temperature values.
Enabled: ACPI thermal management uses DTS SMM mechanism to obtain CPU temperature values. << Try setting enabled, EC may over-ride that, but worth trying.
Out of Spec: ACPI Thermal Management uses EC reported temperature values and DTS SMM is used to handle Out of Spec condition.

You may need to ask Asus why EC FW is only invoking fan at 95C no matter what you set in BIOS, could be a BIOS bug (it is to me), and maybe no one reported it yet. You said stock was same too, correct?
Was it always that way? If not, maybe you need EC re-flashed, it's corrupt etc (only w/ Asus help, or flash programmer can you do that) I can probably get you an EC FW file if you have programmer (don't have time to look back about this right now)

As far as changing EC, no, I don't know of any tools that work with EC FW. It could be done via hex/assembly, but I wouldn't even know where to begin looking at that since it's not something we usually play with.

Thank god ,finally I have found out the culprit .The culprit was the concentrated dust,yes lot of dust have been concentrated in between the fans and the radiators.Literally there was no place for the air to come out .I feel sorry for my fans becuase I was blaming the fans while they were trying hard to push the dusts out. Now I can hear my fans boosting at active trip points .My lappy now overclocks like a beast, my gtx 1060 stays above 1800mhz and my cpu always sits in the max clock(provided the temperature stays well below 80 ) when both are in 100% load.

@kiranfdo - Aha!! So, now fans are working properly and temps look decent? Since it was that bad, original thermal paste is probably turned to thick sludge crap by now too, I would put on new thermal paste if you have some (if not, order some soon)
If I was you, I would re-load optimal defaults now, to put all those settings you possibly changed back to normal, and see if it's OK like that, then OC as needed (Thermal settings probably fine as they were/default)
Great to hear it's all working like you wanted now

How to flash this BIOS?

@Lowapm - You cannot, well should not, flash any BIOS here, they are user specific to the OP (contains his board details, which would replace yours, so not good)
You need to dump BIOS region with FPT, and then let me know what you want changed

Error 201: [FPTw64.exe] cannot be run on the current platform.
Please contact your vendor.

@Lowapm - First, please follow directions exactly FPT can brick your system in one click, no one mentioned using FPTw64 here, so please only do as instructed.

Show me an image of the entire CMD window so I can see if you are using Admin CMD and what you are typing and the output error.
Additionally, what is your ME FW version?

FPT-9.1.10.1000
admin CMD

I can do backup
and i try your Unlocker version
but it's not give me invisible function
SORRY FOR MY BAD English

I want to get all hidden functions

@Lowapm - You need to use FPTw.exe from ME System Tools Package V11 r32 (Intel CSME System Tools v11 r32 - (2020-06-06)) from this thread, section C (not V9 as you are using in your image above at post #27)
Intel Management Engine: Drivers, Firmware & System Tools

Exact command you need to type, from the Win32 folder >> FPTw.exe -bios -d biosreg.bin
Then >> FPTw.exe -bios -f biosreg.bin << After that, show me the error you get

CMD Prompt MUST be Admin CMD Prompt

I use AFUDOS for save and load bios
