RM520N-GL DHCP Server Settings

I am working with a RM520N-GL module and attempting to integrate it into an existing network.

I have read that it is possible to use the “LANIP” command to change the start, end and IP address of the DHCP range and server.

In the current network we already have a DHCP and DNS setup, is it possible to disable the DHCP server on the RM520N-GL module?

Is there also a possibility to configure a static route from within the RM520N-GL, I would like to point the device to a router in our local network.

If these settings cannot be changed by AT commands, can these settings be changed by gaining ADB access and modifying/disabling DHCP service manually and updating the routing table?

Module is R03 running RM520NGLAAR03A04M4G_A0.301.A0.301

Many thanks

Dear @nickds
Sorry, for standard solution, there is no way to disable DHCP.
