How to invert FN keys on Xiaomi notebook

Subj. The problem is that by default F1-F12 on Xiaomi Notebook Air act as a FN keys (adjusting sound, screen brightness and so on) and not as F1-F12. So every time I need F1 I actually have to press Fn + F1 or to toggle "Fn Lock" (Fn + ESC) before.

Some of the existing answers say that there might be an option somewhere in BIOS to invert that, but I was not able to find it.

So how do I invert FN keys on Xiaomi Notebook?

P.S. I'm using Manjaro / Arch Linux, but I want a hardware / BIOS solution if possible.

I came looking for an answer, because it has been driving me crazy, but just solved it myself (on the Mi 15" pro, assume the same one air):

Fn + Esc inverts it, easy!
