only on ESP32-S3-USB. this fiddles with the available hardware UARTs to make it possible to use a third Victron MPPT. if three MPPTs are defined int the pin mapping, you will not be able to use the SmartShunt and JK BMS battery interfaces. note that using a second MPPT will also conflict with the SDM power meter, and that conflict is not detected, yet.
