Looks like you're right that it doesn't yet. It's not mentioned in the changelog and what looks like the relevant ticket for it looks reasonably active but still open. But there was some discussion about a patch in March 2020 so I'm not entirely sure. Does VLC play it?
There is supposedly a branch of ffmpeg (not 5.0) at https://github.com/richardpl/FFmpeg/tree/ac4 that supports AC4 decoding but as far as I know the patch(es) never was/were accepted into the main build of ffmpeg. I don't know why and I'm not a programmer, so I (like probably many other users that have ATSC 3.0 available in their area) am waiting for a static build that supports AC4.
