I’ve found the best solution for that is spinning up an ErsatzTV docker instance and add the Live TV channel to Jellyfin. You can customize what gets played to the Live TV channel and I had used it to run a “kids TV” channel at home. The only drawback is I had to shut it down because the transcoding for it was brutal (on a server with no video card). It will convert everything to a standard stream format, and none of my video files would just get served as is.
