Can not change camera view's properties when start VR Window

I started a VR but i cant change Focal Length, Clip start and Clip end of the camera. when I edit the value, it reset to the origin value.

This is normal behavior because the camera's focal length, clip start and clip end control how you see the scene in VR and are updated automatically to match your headset (field of view) and zoom level.
