Where can I connect FrSky X8R using SBUS on Dronecore 2.0?

Hello,
I am in the process of carrying my old setup of Raspberry Pi 4 + Pixhawk to Dronecore 2.0, which is a combination of Cube+ Orange and a powerful computer.

Unfortunaly, the pinout does not have an RC IN or SBUS port. Is there a way I can change one of the ports through parameters to use as an SBUS connection?

Solved!

It turns out it is located on the underside of the PDB. I connected X8R to the PPM port and now all is well.
