Access aux/relay pins on Pixhawk 2/3DR Solo - for camera trigging

Is it possible to access aux 1 (pin 50), (or other aux ports and ground pin) in 3DR Solo (Pixhawk 2). I need it to trigger a Sony camera with cam_trig_type: relay, which is quite trivial on pixhawk 1. 3DR support wouldn’t help me out with this…

Regards Are.
