GPIO Pins In WisGate EDGE Product Line

Hello,
Does anyone know if it is possible to expose any GPIO pins inside the WisGate Edge Gateways? I am trying to control a relay and didn’t want to add an additional SBC inside the enclosure…

I see there are mpcie expansion slots available on the boards. I can’t seem to find any details on what might be supported. For example, could I just insert the following card?

Any thoughts are appreciated…
