Unity Sync Meta Avatar with Hand controller

Hello, 
I am using the OVR Player controller with OVR Hands, tracked by the device controller, not by the hand tracking system.
As next step, I add the new meta avatar below the OVR Player controller (exactly below the TrackingSpace transform), keeping the OVR Hands logic, because I need to interact with other objects. 
However, the OVR Hand hand model is not synced (does not overlap) the meta avatar hand. 
Is there a way to fix, fine tune, that issue? I cannot use the hand tracking system, I need to use the device controller for tracking hand rotation and position, but replacing the controller model with hand one.

Thanks in advanced for any help.
