Hi, Not sure if I can help other than to say that under LL6.0 RC1 the touch pad and screen back light work OK on an Ideapad Gaming 3 although the keys are different for screen back light to those on your model (in my case Fn+F5 for darker and Fn+F6 for lighter).
I chose LL6.0 for its nod to accessibility and in my case the need for a keyboard back light but unfortunately this does not work yet (Fn+SPACE) in LL6.
Interestingly in my case, your distro. Ubuntu 21.10 https://linux-hardware.org/?probe=47907aec3e shows the keyboard back light to be OK on my model.
Perhaps generate and upload a probe of your hardware and compare the results with what others have posted.
