For RealDrums, you cannot, other than maybe applying something like selective multiband equalization.

For MIDI drums within in BIAB, they are only going to be on MIDI channel 10 and on the single drum track. It's a lot of work, however, but you can edit the individual notes (which represent the instruments played) using the piano roll editor and changing velocities.

Or, you could export the drums to a MIDI file and manage each part separately in a DAW (such as RealBand, for example), where you can export MIDI drums from BIAB to separate tracks. See page 216 in the BIAB 2015 user's manual in the "Saving MIDI and Karaoke Files" section.

You could also load a BIAB file in RealBand and (you will probably have to) convert BIAB tracks to regular tracks, then you can split MIDI drums to separate tracks from within RealBand. Of course, make sure you don't have automatic RealDrum substitution turned on, otherwise you will get RealDrums instead. See page 98 in the RealBand 2015 user manual for how to do this.
