Problem when trying to extract rom using afuwin64

[zenna]

Good I have a motherboard: asus tuf gaming x-570 plus, I'm trying to get the rom through afuwin64 but I get the following error: 18 - error secure flash rom verify fail.
I want to make a modified bios to change serials as well as the uuid and serialnumber and try to flash it through the ez utility that has the motherboard.

If you could help me with this issue I would appreciate it very much,
Best regards.
