Custom resolution on Silverblue Nvidia wayland

I wonder how to set up a custom resolution and a refresh rate, or when it will be possible to set it up on Silverblue with Nvidia?

Maybe someone knows?

Thank you.

You should be able to do this from a Gnome setting. Look up custom refresh resolution Gnome.

I cannot figure it out. There are guides on how to do it on Ubuntu or with x11, but not on Silverblue. Its file system looks a little different than Ubuntu.

I also tried AI help, but I do not know if I can trust it - might be hallucinating : D

It told me to add it to kargs, but nothing changed in menu.

rpm-ostree kargs --append=“video=eDP-1:1920x1080@60”

I wish Gnome settings, would had such a thing. Maybe someone could write a simple guide on how to do it?
