[Problem] Recreating UUID to flash a dead ASUS MB (ROG Strix B450-F)

Hi!

As the title says, a year ago my Asus B450-F MB died after a failed bios update, not long ago i got a CH314a programmer and desoldered the bios chip and did a read on it, all i got was garbage from the failed update itself, nothing to recover (also i lost the original backup as the drive where it was died suddenly), i have the SN and MAC Address from the stickers on the board itself, but i got no luck with the UUID, as far as i know, UUID is used for certain software (Windows itself for activation purposes and some anti-cheat software uses it too), i used the uefi tool to extract the capsule and mod the values with FD44, but i cant recover a valid UUID to use in the board, at this point im pretty sure that the UUID is just a static value plus the mac itself to make it unique, but i cant get a example of UUID for this type of board.

How do i proceed in this case? at this point this is just for learning as i dont need the board.
