Gigabyte B550M – Unable to Generate a Patched BIOS

[mikuzz]

Hello,
I'm looking for support

System

• Motherboard: B550M DS3H (Rev. 1.2) / (I'm on F21a) support Resizable bar since Bios F12

• CPU: Ryzen 5 2600 (Pinnacle Ridge) - not in the list of supported CPU for gigabyte

• GPU : Intel Arc B580 (connected using M.2 NVME with Oculink) - This solution worked well on a HP 800 G3 with Intel i5-6500 or similar

• [X ] CSM is turned off.

• [X ] 4G decoding is enabled.

• Re-size BAR is not visibile in the Bios Setup

• UEFIPatch is applied
  I try to apply UefiPatch but with Bios version f21a (and some of the previous F20, F19 ,etc)

UEFIPatch.exe biosf21a.fd
parseSection: GUID defined section with unknown processing method
parseSection: GUID defined section can not be processed
parseSection: GUID defined section with unknown processing method
parseSection: GUID defined section can not be processed
No patches can be applied to input file

With Bios version f10 (then before introduce re-size BAR)

UEFIPatch.exe biosf10.rom
parseFile: non-empty pad-file contents will be destroyed after volume modifications
parseFile: non-empty pad-file contents will be destroyed after volume modifications
No patches can be applied to input file

How I can proceed?
