[REQUEST] Acer Nitro 5 AN515-43 BIOS Unlock

[AntiVirGear]

Hey there,

I AM willing to do it myself but more because I want to learn something new and I also kinda like to have a challenge
BUT
I have to start somewhere and I need someone professional as assistance :/

So far;
Acer Nitro 5 AN515-43-R0FC (R0FC is just a variation w/ 2x4GB DDR4 and 512GB M.2)
Bios Ver.: 1.08 (InsydeH20 ?)
Link: https://global-download.acer.com/GDFiles...1416111423
Unlock: Everything possible :D


I also own a CH341 programmer incl. clamp (duh) which works fine, I can create a dump (if I find the bios chip... was on Asus easier)
I also know setup_var which I tested out and it found something to use but I'm not sure, I'll post everything I get so far...


I also tried to find any information about bios modding and setup_var and more by myself but these infos seems to be scattered around (or Google Search isn't configured properly for me  :P )

For some models I saw that there is a setup_var for changing the access levels (Link)
But I don't want to brick anything until I have a bios dump! (I'll try to get it this weekend)
I also would guess that they don't work since I have everything AMD and not Intel/Nvidia...
But I'm curious where they get all these variables :/



I hope someone can help me out and have a nice day :)

I'm looking for a way to enter the advanced mode in my Nitro 5 AN515-43. There's supposed to be a way to enter the BIOS without flashing anything, there has to be someone somewhere that knows how to enter this [censored] advanced mode without flashing.

Alternatively, if anyone knows, I would like to know how people usually get access to the keys used to enter other BIOS' advanced modes. Is there any way to get it reverse engineering the BIOS or is it just leaked information from Acer?

I just want to play Cyberpunk, what the [censored] is wrong with the guys responsible for this laptop? Why would anyone in their right mind put 2GBs of RAM towards the iGPU when you have a dedicated GPU with 4GBs of DDR5 RAM just there???
