I believe you can achieve that by using an exernal player that can output to HDMI frame pack (I don't know any), or you can look if another format is supported by your projector, like Full SBS ou MVC ( that would be much much easier).
As you said, it is theorically possible to convert most 3D formats to HDMI frame pack with ffmpeg, but I believe most projectors won't trigger the 3D mode if you send the video file in that format directly, it has to have some special instructions given by the player ? Not sure about that part, as my own projector doesn't do frame pack. So maybe you could just try to make one file for a test, it should be as simple as
and play that file on your projector directly to see if it plays in 3D. If that works, then there is hope, maybe you can achieve your goal using Jellyfin MPV shim with an external MPV and a custom command, or something similar.
