In which case it should be easy enough to solder a jumper onto the PCB that has the effect of shorting out the stop/start switch and permanently disabling SS.I don't think you can. I opened up that central console with the idea that I'll mount my bass control knob next to the volume knob. The entire back of that panel is a printed circuit board with the buttons soldered onto it. Can't easily add, remove or modify anything there.
If anything this should have been individual buttons, I would have loved for this to be more modular.
