[Request] Modded Acer Predator Helios 300 PH315-54-760S BIOS

In my helios 2019 this option was uncheck from factory (acer permited to undevolt as default), this 11th gen of predator 2021 no, i need to disable this option to allow the undervolt, but tks to clarify me, now everything is fine. The only thing is when i try to change the PL1 time window in BIOS, the machine frozen, I only can do this using XTU in windows…

Is it possible to extract vbios from bios?

it’s pretty simple really.
