Rules on this seem slightly grayer this year. There's not specific prohibition on adjusting the switch, just that it needs to operate to prevent over pressuring the system. There's the general rule prohibiting modification of pneumatic components and there's no exception for adjusting the pressure switch, but there's also no exception for calibrating the pressure relief valve, which is suggested by a blue box later on.
Maybe Q&A adjustment of the pressure switch just to be sure?
