Rak7289cv2 no restart lte module

I have purchased 10 RAK7289CV2 todayupdated to the latest firmware version 2.1.6 , the version is eu868, unfortunately I had a bitter surprise. For my project the conectivity uses LTE data SIM and haime I found that the gateway does not reset turn off or reboot the cellular module, the only way is to disconnect the:power. Can anyone help me, is there any correction that can be made?
