Showing Hands for controllers, NOT hand tracking

Hi my use case is I need the controllers and not hand tracking.  However, I want to render the controllers as Hands in VR.  I am interested in doing this with only the Meta SDK and not the Unity Interaction SDK.

Can someone clarify what the difference between OVRControllerDrivenHands and the OVRHandPrefab is?  Also, I can't seem to find any good documentation about these, where can I find that?

What I have tried so far that does not work: Drag the OVRHandPrefab under the Left and Right AnchorPoints under the OVRCameraRig and set the OVRManager to Hand Tracking Support to: Controllers Only.  They work when I set them to Controller and Hands, but not Controllers Only.

Am I supposed to use the OVRControllerDrivenHands if I only want Controllers that look like hands?

Thanks.
