First, thanks for answering.
In the end I managed to make the modification with AMIBCP, use the following guide to achieve it. [Guide] How to flash a modded AMI UEFI BIOS
When I flash the bios, I see that the options were saved as expected, but when I load windows everything freezes.
Finally, I was already asking in the “REBAR thread”, but according to the knowledge of the people who tried to help me… there were no new alternatives. I’m still waiting and trying things in the meantime.
