I recently purchased the xiaomi redmibook 14 II ryzen edition (4500u, 8gig) for school. I set up a dual boot for windows and arch, however I would like to have more control over setting the voltages (undervolting, GPU tuning, etc) and being able to change settings relating to S3 “connected standby” sleep behavior since that is completely broken on linux. (I have to use hibernate on lid close because of backlight issues, not to mention the backpack furnace potential when running windows).
Sadly however the bios is locked down more than Alcatraz and besides secure boot you really can’t change anything at all.
Below I have the link to the official drivers, the page is in chinese and loads incredible slow but it works:
(edit, since im a new user im not allowed to link pages so use the stuff below to get to the link)

I’m reasonable technical so i’d be 100% willing to put in work, i’m just really clueless as to where to start and what to do.
