There is not anything in the UI for it, but you could probably kill the process while in SSH. Do you have a particular intent? If you do not add any Z-Wave sensors the Z-Wave really has no point anyways, so I would want to know the use case before more ideas. Otherwise, this might be something to move to the Ideas section, adding a method to turn off the ZigBee and Z-Wave (if someone has not already raised it).
