Mavlink to FrSky S.Port Passthru Converter for LRS or PX4 Pro

I am attempting to use MavToPass in relay mode with the SIYI HM30 video/telemetry unit and an Archer RS in FPort mode. I intend to use an ESP32 connected to the UART and RC ports of the HM30.

The HM30 requires SBus on the RC port, and according to the wiki:

With a few tweaks Mav2PT can decode the RC control telemetry and output it as SBUS, PPM or PWM.

It looks like those “tweaks” are not yet implemented - is that correct?

Is the intent to implement those tweaks in the presently empty #ifdef macros for Support_SBUS_Out?
