increase draw distance of OVRCameraRig

Hello, I am developing a VR app for the Oculus quest where you are placed on a terrain. I am using the standard OVRCameraRig provided by the Oculus Integration SDK as camera. Now I want to be able to see the whole terrain, but at a certain draw distance the terrain stops rendering. How do I increase the drawe distance in this scenario? I didn't find a way to increase a kind of far clip plane, as suggested in other answers for this topic.
