Apparently, the Windows version of the Zoom client will happily do virtual backgrounds without the need for a green screen (providing your hardware meets the minimum requirements). But then if we were Windows users, we wouldn't be here would we?
Unfortunately, that facility is not available to Linux users and, last time I checked, I don't think it is planned - probably down to lack of demand / pressure.

Just a few days ago the BBC had a story about second-hand booksellers
doing a nice trade in selling batches of serious-looking books that
people could place strategically behind them :-)
