CrowPanel CM-4 7" display - driver to expansions modules

in Elecrow HMI Display

I bought a CrowPanel CM-4 7" display from Elecrow. I ordered the two options G4 and Lora (WiFi) at the same time because I might need them later.
Now I have to realize that if you order these options, certain interfaces such as RS485 are no longer possible. It's a shame that there is no indication when ordering that if you choose an option, certain interfaces will no longer be available. It would be nice if this could be added on your website.

Now I need to know which drivers I have to uninstall so that I can have the interfaces I need (2xRS485) available again. I'm still a beginner with Raspberry Pi. I'm not using G4 or Lora at the moment.

Thank you very much.

    Hello,
    You don't need to uninstall the driver, the RS485 will work when you turn on.
