Crossfire/ExpressLRS on Holybro PX4

HI!
Is there any actual support for CrossFire/ExpressLRS on FMUv5x?
For reference, I am planning to use a Holybro Pixhawk 5X and BetaFPV Nano receiver.

I do not really need telemetry pass-through to a ground station, but basic telemetry to the radio would be nice.

I think this might be possible if you are comfortable with compiling. I haven’t tested it yet.
