EC25 disable when FC20 wifi enabled

IoT Modules LTE Standard Module
1

I am using an EC25+FC20 board.

  1. The EC25 module is currently connected to the LTE network.
  2. Enable the FC20 module and connect it to an external AP.
    In this case, is there a way to disable the EC25 module or prevent it from being connected to the LTE network?
    In conclusion, I want to disable EC25 when Wifi is enabled.

Is the EC25 OpenLinux version?
It seems that you want the FC20 works in STA mode.
