I believe it would depend on your desktop environment/window compositor/manager.

I don't think there's a single one that works for everything, but you could try wdisplays or kanshi or wlr-randr

Check https://arewewaylandyet.com/ under "Output/display configuration tool" to see the different ones

Here is an example using wlr-randr for HDMI-A-1:
wlr-randr --output HDMI-A-1 --mode 1920x1080@60Hz --scale 1

No.

But there may be options for some individual compositors. Which compositor are you using?

wlr-randr will "work" with wlroots-based compositors, however I doesn't set the refresh rate as xrandr can; the protocol used by wlr-randr only sets position, size, scale, and transformations for the output. There has been some talk of it, but I don't think wlroots provides a way to set specific refresh rates. Sway has been patched to allow variable refresh rates - but this is still not a user-specified rate.

So you need to look for the KDE (not wayland) way of doing this. This should be in the screen / outputs section of the settings app. I've seen references to command line tools kscreen and / or kscreen-doctor which may be available - but I don't really know KDE.
