You should be able to make serial data exchanges between the MKR WAN 1300 and the Controllino pin header.
The Controllino Pin Headers allows access to the ATmega328P processor, just like you are using a regular Arduino UNO. Once they are connected, then it seems logical that the MKR WAN 1300 could send commands to Controllino.
I have not tested this and have never used a MKR WAN 1300
