Unlock Acer Aspire 3 A315-58 BIOS advanced menu

I wanna request for my Acer Aspire 3 A315-58 bios’ advanced menu to be unlocked, the embedded controller keeps controlling my power limits and I want to set it so that not only I could change the power limits, but also to be able to undervolt if the hidden advanced menu shows so.
Specs:
i3 1115g4
Intel UHD for 11th Gen
12GB Ram
Insyde H20 Bios Version 1.28, Rev. 5.0

Notes:

  • Acer BIOS is said to be write-protected according to related BIOSes from the bios-mod forums.
  • I also happen to read a thread from MyDigitalLife about this laptop (https//forums,mydigitallife,net/threads/acer-aspire-3-a315-58.83703) as well as the methods in unlocking it, but there weren’t any updates or results about it since 2021. I have also read a topic here that involved a similar method from the aforementioned thread ([Request] Biosmod Legion 5 15IMH05 - Unlock Advanced Features) and if possible, maybe it could work on mine.
  • I’m aware of the backup part in the second thread and how it works but I still ask to be guided if possible to avoid issues because I am only 17 and I can’t just buy another laptop directly.
    Thank you in advance.

@Sweet_Kitten could you have a look if you have the time?
