Maybe you could tru wlr-randr.

I do not know how that works in Gnome env...

Nope. wlr-randr uses the wlr output management protocol which is currently only supported by sway and wlroots-based compositors.  It's likely that it could be adopted by plasma/kde and other QCompositor-based compositors* (as KDE tends to be a team player) - I suspect hell will freeze over before gnome/mutter ever cooperates with supporting a protocol they didn't write.  So no third-party tool could ever achieve this: if gnome itself doesn't provide a CLI interface (which I'm pretty sure they dont) then there wouldn't be a way to do it.

*note: KDE has their own output management protocol, though I'd wager it is being developed in parallel with the wlr protocol and will eventually be merged allowing for interoperability of KDE / WLR tools.

There's gdctl for that now! For example, I set my monitor's mode like this:

gdctl set --logical-monitor --primary --monitor DP-3 --mode 5120x1440@240.000
