ROG Ally VRR

I probably being stupid and missing the obvious but I'm struggling to find an answer online.

I've just installed Bazzite on my all and it says in the Steam power setings that VRR is not supported even when using the devices own display. Is this correct or is there a step I'm missing?

Solution

Scratch that, found it. For anyone else toy need to go into desktop mode, into settings and then in to Display.
