Setting low persistence mode with latest Unity

I would need to disable low persistence mode for testing purposes, but the OVRDevice.SetLowPersistenceMode(false) function does not seem to be there anymore. I found out about the function from this discussion: https://forums.oculus.com/developer/discussion/14874/any-way-to-disable-low-persistence

I am using Unity 5.3 and Oculus Utilities 1.6.0. Has the possibility to set the low persistence mode on/off been removed completely?

Also the OVRManager.capiHmd is not available anymore. How could I set the low persistence mode now?
