No, there is no need for that. All settings can be done with the 860C
The java configurator does that for stock display which can not be programmed.
If there is a Tsdz2 combination, where the 860C can work with stock firmware, then you only need to flash the controller with OSF with the java configurator. The same as with stock display.
In the past there was such a combination wit SW102 for sale, but never seen this with 860C.
