I think gnome boxes uses libosinfo for proposing OSs. There is already some data about Guix at https://gitlab.com/libosinfo/osinfo-db/-/tree/master/data/os/guix.gnu.org

However, we only propose an xzipped iso (and not a raw iso file), so the data does not provide information on downloading. Either we have an outdated osinfo-db, or the lack of download option prevents boxes from showing it as a choice.
