If the one you have is the same as the one I am fixing for a client, then "NO easy commercial solution" is the answer.
You will need to change both the controller and driver. The one in my workshop uses resistive circuit and 1W LEDs, therefore, dimmable constant current driver suitable for it is not easy to find.
Actually there is another way to make a controller for it but I have no time to build an MC base controller to instruct the remote to do things. That is to simulate your hand pressing the buttons. I can ask my technician to see whether he wants to build one that way.
