Now grab the resulted “x64_bios-region” file, extracted from the RAR, apply the mod according the guide, use method 1 or 2 and share it again for verification before flashing, if you want it.
Recommended method, AMI MMtool and small DXE variant.
The “verification” is also described in the guide using UEFItool for missing/added PAD file on selected bios volume.
For flashing, get the ME9.1 tools package from C2. (CS)ME System Tools and use the Intel FPT tool as CMD line ADMIN, preferably on the root of a disk:
Ex.: fptw64 -bios -f x64_bios-region_mod

Its a user choice ONLY regarding the risks of flashing mod files.
Good luck.
EDIT: Use the MMTool_x86_5.00.0007
