Not everything however. For it to catch some options , for example SOCKS bridges, you have to use the SSH passthrough notation aka rsync -e 'ssh bridgename...' --rsync-options.... And ofc if you have to load a different SSH conffile, you have to use the while passthrough for that as well, there's no rsync native option to load a SSH conffile: rsync -e 'ssh -F conffile ssh_options...' --rsync-options....
