Quest 2 - Force 3DOF for project

Hi, how can set the project I'm working on to 3DOF only?

I disabled "Use position tracking" on the OVRCameraRig component, it kind of works, but the visual result is quite different from disabling "Tracking" on the device ( quest 2 -> Settings -> Device -> Tracking).
The device tracking turned of behaves as it should, but disabling it on the CameraRig distorts the panels a bit when looking around, looks really bad.

Is there another way to force the app to go 3DOF?
