FFR in Unity OpenXR on Quest 2?

Hello!

My team is having some frustrating issues with visual clarity in our Unity project built for the Quest 2 with Unity OpenXR. The clarity is especially abysmal (blurry, distortion) towards the far edges of the screen, which begs the question: is fixed foveated rendering on or off  by default with Unity OpenXR? Or is this setting not controlled by Unity at all, and just from the headset menu? If it is on (which it looks like it is in terms of degrading quality away from the center), we would certainly like to turn it off!

Many thanks,

Lorenzo
