Hey there wenyingyw! This is a great question, many other users have wondered the same in the past. At this time, it's not quite possible yet to enable both hand and controller tracking. We'd love to hear feedback from our community regarding this, if anyone has any additional insight please let us know! You should also check out our Unity VR Development forum to get in touch with other developers.
This would be very useful for training apps. where one controller is tracking an object (like a crane controller) and the other hand is touching the buttons.
The new htc standalone headset has this feature. i really need this feature on quest too.
