[Request] Unlocked Acer Predator PH315-53 BIOS v2.04

Hello,

I would like to request an Advanced Menu unlock for my Acer Predator Helios 300 (PH315-53).

My Goal: I need to access the advanced graphics settings to find the Mux Switch (Display Mode) and set it to “Discrete GPU Only”. This is to allow me to run diagnostic tools (MATS/NVFlash) from a bootable USB, as they cannot detect my dGPU (RTX 2070) in Optimus mode.

Model: Acer Predator PH315-53 BIOS Version: v2.04

Here is the link to my BIOS dump, created using FPTW64: BIOS DUMP – Google Drive

lol out of luck then, you have to dump it first using programmer to replace the BIOS Region in UEFITool 28 with the file i’ve provided before.

or

SREP (i can’t help making a config for this device as I’m as well still trial and error)
