Per this previous thread I need similar assistance thanks.
downgrade me firmware
Running 3802 firmware and I need that ME Firmware into my system.
Per the linked post I get most of this, however I don’t know how to extract the BIOS via UEFITool? Also, do I re-name the boot64.efi to shell.efi and keep at root level? Can anyone please expand on these steps so I can process this.

Rename your .efi file to >> Shell.efi
Me FW Image Re-Flash variable to edit >> 0x6A9
So at grub prompt, type the following >> setup_var 0x6A9 0x1
Now, ME FW will be disabled, some things might not function properly and fan may run full speed etc.
Then take BIOS from your board that has the ME version you want to use in it, extract BIOS body from capsule using UEFITool
Then flash ME via FPT >> FPTw.exe -me -f biosbody.bin
So I ran UEFITool and extracted the ME Region from default BIOS which is 2548kb. I then ran FTP to extract installed ME and it comes out same size. I think I therefore have the correct ME from the BIOS (extracted via UEFITool). Next step is to run the shell and disable ME, then install via FTP -ME -f [file]. Does this sound right?
