There are some attempts to change the number of outputs in PX4 for SBUS, like Commits · OskarPepryk/Firmware · GitHub, which is running on an older version of PX4. I personally didn’t try it yet. I think it might also be an hardware issue, since the Cube Orange, for example, indicates that only the 8 MAIN OUT channels processed by the IO chip are sent through the SBUS port. Which board are you using?
