Decouple head from body movement in VR

Hi all,

I am working on a VR project and I would like to decouple the movement of the OVR Player Controller and the movement of the OVR Camera Rig.
I mean, usually the direction of the player is linked to the rotation of the head. I would like the player to be able to turn around their head and keep moving forward.
I think it is possible to do that, but I am not sure how to do it.

Thank you
