Acer nitro n50-620 bios unlock / specs problem

[prosmoldermain69]

Hey, i happen to have a strange bios related problem with my Nitro n50-620. it has a b560 mobo, but it shows up everywhere as an z690 aorus elite ax... in hwinfo, and even in the bios which makes me come here as i am 100% sure its the bios, ive tried updating the bios, clearing cmos, and diffrent operating systems. the broken specs are just hardstuck everywhere, and an update dosent restore it. im pretty sure my only way is to use an "CH341A EEPROM programer"? which i dont have, nor have any experience with raw bios flashing. it would be nice if someone could take a look into my bios for any hidden menus, or specs information. i guess the factory specs gotta be in the bios update file, but they dont copy as a part of a bios update, it might need a full reflash?
