There's a few ways:
===============================================================
If you don't want anything to play on the track, you can either:
1. - disable the track

or

2. - select a silent RealTrack for that track (one of the RealTracks is silence, #1152. If you forget the #1152, you can just type silence as a filter.
==========================================================
If you plan to add something else on the track, like a MIDI SuperTracks or a loop, you can just choose that, and the RealTracks will not play.
==========================================================
If the style contains an underlying MIDI part, that would get played instead of the RealTracks, and you want that MIDI track to play:
- disable the RealTracks in the RealTracks picker (this will instead play underlying MIDI, so you may not want this option)

Have Fun!
