FC is LUX V2 Race F3 BTFL 3.5.7 Betaflight configurator 10.7.2 it was not possible to flash more current firmware on this board.
Sooo, Betaflight does not even show OSD or Video Transmitter pages. Does that mean no Betaflight OSD is possible?
I have been flying it with a Foxeer camera that uses a wire to battery to show total batt voltage in the goggles OSD, that, a name, and time powered up are coming from the camera. I don't think there is a way to get betaflight OSD info even if I got a new VTX. Just checking here that I have done all I can with this.

If it is true that I cannot have Betaflight OSD with this FC then maybe I have some housecleaning to do, there are settings I did not choose. I installed a TBS Crossfire Nano Rx. In the Tx Lua (Boxer with OpenTX) CH1 is CRSF TX and CH2 is CRSF RX fine, but CH4 is SmartAudio, maybe I should not have that there? And in the Ports tab UART5 has VTX(TBS Smart Audio) selected. Probably shouldn't. Note that this LUX FC uses UART4 for Serial Rx.

The Lumenier LUX V2 FC doesn't have a 28-pin MAX7456 / AT7456E OSD chip on it, so you are unfortunately out of luck with using Betaflight OSD on that particular FC.
