It seemed like Anderson was considering a return (https://www.quora.com/Why-has-Richard-Dean-Anderson-not-returned-to-television) when he did a short story arc on the series Fairly Legal in the 2010s. However since that was his final IMDb (https://www.imdb.com/name/nm0000760/) credit and that was 2013, it seems that he’s decided to retire (https://www.reddit.com/r/Stargate/comments/ulbd4n/just_found_out_richard_dean_anderson_is_retired/) (voluntarily or not) from the entertainment business.
