Error 318: The host CPU does not have read access to the target flash area. To enable read access for this operation you must modify the descriptor settings to give host access to this region.
FPT Operation Failed.

I have to do Dump SPI with Flash Programming Tool, follow the cleanup guide and flash back followed by fptw -greset command. - right?

No, and you can't dump ME region due to error shown in #8, ME region is locked. Do you have backup of BIOS before this happened? Please wait for plutomaniac to reply again, so it does not get worse situation.
Your ME is corrupted right now, I think the only way to fix is by using FPT and a correct type BIOS that contains working ME after doing shorting method (Pinmod) to enable FD/ME access, or with flash programmer.

Check your motherboard while you wait, and see if you have any two-pin jumpers labeled ME, FD, or Service - or any unlabeled two-pin jumpers (Add image to show us if no label)
I will check stock BIOS for you now and see if it's an option or not. Do you use N21 or N11 type BIOS, if you are not certain, please check and see if CPU-z motherboard tab shows either of those, or link your BIOS download page
Is this your exact system? https://support.hp.com/us-en/drivers/sel...mini-pc/8741496

This system might have HP's "Surestart" recovery features, we ran into that with the tower version - RE:HP EliteOne 800 G2 CPU Gen6 to Gen7
Maybe you can enable this and specifically ME setting for it in the BIOS, I am not sure of all the options for this, or if your smaller version has it? But when we changed his ME it auto recovered, so maybe you can mess with that if it's in your BIOS and get it to fix itself.

We also had to use flash programmer on his, so I assume you will end up needing for your system as well. Go ahead and order now, CH341A and SOIC8 test clip w/ cable.
But you can see if FPT will give you full dump using this command, 16MB dump is what you need to see otherwise it's not complete.

I assumed it would fail, that FPT dump. You're going to either have to short the board (Pinmod) per the guide
Or get a flash programmer, unless Plutomaniac has a method

Wait, I see FDO jumper (Furthest left two pins in your image) - you're in luck, see here for how that's used
[Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing

Put that jumper on, and then run the dump with FPT again I gave you, then we can fix that file for you (Or you can) then reflash it via FPTw -f fixedbios.bin, then shut down, remove jumper and get into windows and run FPTw -greset
Keep a spare copy of the backup dump safe, not edited somewhere, that way if you can't get it fixed and we have to fix then it will be a clean unedited file.

*Edit, plutomaniac ninja'd me hey man, sorry to jump in on this, but was reading so thought I'd help!

in the leftmost position FDO - PC not start "screen 1"
in the middle position BB - PC start in vga mode "screen 2"
