Cubase + NI S49 MK III: Hiding Midi in Mixer

I have connected my NI S49 MK III to Cubase.
The MKIII hast a Mixer for the Daw. Is there a possibility to only show Instrument/Audio Tracks in the Mixer. I don’t won’t so see the Midi channels.
In the mixer on the project I already filtered MIDI channels, but they don’t disappear from the mixer in S49 MK III.
