Allow Optional 3DoF Head Tracking doesn't work

I've enabled checkbox "Allow Optional 3DoF Head Tracking" in OVRManager Quest features. But my app still can't start when headtracking disabled (for example in low light room).

I've checked manifest and i see that:

<uses-feature android:name="android.hardware.vr.headtracking" android:required="false" android:version="1"/>

How to add ability for app to work without headtracking? I see that many apps can work without headtracking but i can't understand how to do it.

On this manual https://developers.meta.com/horizon/documentation/unity/unity-ovrcamerarig/#general i see that "Allow Optional 3DoF Head Tracking" must allow this.
