Give this a shot.

Download Ventoy for Linux:

Download an .iso image of Hiren's Boot CD - this uses a WinPE of Windows 10 in Live mode - try to update the BIOS this way by adding the .iso of Hiren's Boot CD to the Ventoy thumb drive.

https://www.hirensbootcd.org/download/

When booting off the Ventoy thumb drive, enter your BIOS to change the Boot Order - you will see 2 entries for your thumb drive - a standard one and an EFI one - you need to choose the EFI boot option for Hiren's Boot CD to work.
