It certainly doesn’t “support” it as such since there is no suitable transceiver on the board.

You can add a transceiver of course, using the 1.8v UARTs or, if you want to use a combo UART+transceiver device you can hook up via SPI or (maybe) i2c. Likewise, for the protocol layer, you can look at https://libmodbus.org/ .
