First, a few facts:

  1. In modern BIOS there is a function to save the settings as a file on a flash drive.
  2. There is also EFI Shell , which seems to be able to work from under FreeDOS (I could be wrong). In the BIOS itself, you can definitely call separately.
  3. Updates from the same Asus work on FreeDOS .
  4. There is a cross-platform Flashrom project that supports a bunch of firmware chips.
  5. Linux can write to UEFI .
  6. There is Intel AMT technology, which generally can do anything and have an official SDK .

Actually the question is : can this somehow somehow tie up everything? There are no problems with updating: Gigabyte and Asus put the necessary version of the flasher with the ROM file and even autoexec.bat . But then how to plug in the settings (turn on VT-x, select First Boot Device, configure WoL) has not yet found.

Ideal solution : Update the BIOS in one reboot and immediately feed the settings file.
