Just got my thinkpad t14s (amd) today! and downloaded Ubuntu surprisingly everything works amazing besides the brightness being stuck at 100% which isn’t to terrible to battery but still drains a bit. I gotta say the ryzen 4000 series on linux is next level battery life in general is amazing.

Try using a tool like xbacklight, light or brillo to change your backlight brightness and see if it works. Should be available in the repos.
