Nope, Aurender supports integrated access to Qobuz, Tidal and Internet Radio. Plus Spotify Connect and AirPlay supporting devices.
I would send an email to support desk and ask if there is way to stream from Deezer.
BTW, I just looked up Deezer doesn’t stream in high resolution, only CD resolution. I highly recommend using Qobuz with N200. If you’re worried about your playlists, you can use freeyourmusic app to transfer all of your playlists, songs, and favorite albums from Deezer to Qobuz.
