I'm trying to send SMS using the SIM7600X on my Raspberry Pi 3B+, but I also have a Fan SHIM installed. The problem is that both the SIM7600X and the Fan SHIM's LEDs are using the same UART pins (GPIO 14 and 15). Whenever I attempt to communicate with the SIM7600X, the Fan SHIM's LED turns on, and sometimes this interference prevents me from sending commands to the SIM7600X. Can I stop fanshim from using those pins or any other workaround?
