display.displayFrequency not setting

Hi there,

I'm using Unity 2021.3.11f1, Oculus SDK Integration with the OpenXR backend enabled.

I'm trying to set the refresh rate to 90Hz, I've got an object in scene with a script with:

OVRManager.display.displayFrequency = 90.0f;

When I build to the Quest 2 - OVR Overlay reports the display refresh rate is still just 72Hz. Even if I drop that line into Update(), nothing changes.

Any ideas?
