Disable Oculus Rift CV1 orientation and position

Dear all

I am using UE 4.13 and I would like to disable Oculus Rift CV1 orientation and position through blueprint scripting. I tried before to do the same thing with Oculus DK2 and UE 4.10 and I was able to disable Oculus orientation and position. However, using the new versions of unreal engine not allow me to find some methods and functions that I used before. Anyone know how to disable Oculus Rift CV1 orientation and position using UE 4.13?

Regards,
