CVT gearbox – Start-stop – Tyre pressure control system

Since I came across the SpaceStar during the second-hand car search, I have the following questions to the experienced users: can the start-stop system be switched off simply and temporarily and be reactivated for the HU investigations? Supposedly a separate cable is located from the battery plus pole to the start-stop system, if this is correct an intermediate switch could be installed here e.g… Who has what experience with the CVT transmission? Since the tire pressure control system via the ABS fun Do sensors have to be installed when changing tyres? Does a SpaceStar itself have an AHK installed? If yes feasible as a hobby screwdriver? Thanks in advance for useful contributions
