Swap GPS UART on a RAK2245 gateway

Hi there!! Hope that you’re all doing fine.
As the topic suggests, I’ve got an ongoing issue with the GPS module on my RAK2245 gateway, running Gateway OS Base 3.4.0
It seems that the GPS module outputs data to the Raspberry ttyS0 serial interface (miniuart) when it should do so to the ttyAMA0 interface. I’ve realised this by doing “cat /dev/ttyAMA0”: there’s nothing in there, all the NMEA data is currently being piped to the ttyS0 interface.
Because I have no GPS time sync, I’m able to use nothing but CLASS A protocol.
Do you guys know if there’s any way to tell concentratord where to look for GPS data?
Thank you so much in advance and stay care!!
