Yes. That’s why you’re lucky, the intel ones are complete wrecks. It also doesn’t matter how much you paid, the legion series are classic “Works With Windows” systems, even if you paid $3k.
This was always the issue with nvidia-only notebooks, the nvidia driver provides scaled resolutions only through randr 1.1
xrandr --q1 shows them. Quite unusable. Don’t know if Wayland handles this better.
Did you check if it even outputs at 60Hz, eg using glxgears?
It’s like something like that, I suspect:

Don’t know why it rejects the 60Hz as minimum refresh rate. Should work but doesn’t.
Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
