Advanced Settings Bios Mod for Acer Predator ph315-54

Hi would anyone know how i can enable the advanced settings on my Acer Predator Helios (PH315-54) have tried the keyboard combinations etc nothing seems to work.

Specs
i9 - 11900H
3070rtx (140w) i have successfully flashed this card to 140w from 110w
32Gb Ram - 3200mhz
Running Bios Version 1.15
Win 11

wanting to unlock the advanced bios setting to tweak more settings - thermals are not an issue for me as running a IETS GT500 Cooler - with arctic MX-4 thermal repaste.

Any help would be welcomed

TIA
