You can try booting to a HBCD PE ISO from Ventoy.

or make an Easy2Boot USB drive and then copy on the DOS flash program and BIOS files to a folder named \FLASH on the root of the first partition NTFS drive.
Then Legacy-boot to E2B - go to DOS menu and select 'FreeDOS (from a floppy image)). Now you can navigate to the FLASH folder and run the DOS flash program
cd \FLASH
dir
