Heltec OLED LoRa v2 Dual-Band

Hello ! I have a question about the Heltec board. This board has a SX127x microchip. Can I transmit LoRa and FSK (or OOK) at the same time? According to the diagrams, there is a multiplexer at the output oh both modulators.Anyone who can provide me with an example would be of great help. Thak you very much !!
