Yes. The Volca Beats notes are listed in it's MIDI implementation chart, well mostly listed, there are a few which aren't on there but definitely are tied to a note number. I'm not near my cheatsheets right now, but I'm sure someone else has listed them and dumped them somewhere on the internet.
If those are your only drum sources right now, put the Nord Drum kick on 37, the Volca Beats has nothing on that number. 37 is right next to 36 and in the same octave as the Volca Beats kick, so no need to change octave to access it.
The next instrument on the VBeats is the snare and it's assigned to 38, which is again adhering to the GM standard and will most likely cross over with the Nord's defaults. But here's where you might want to keep them on both on the same note number. The VBeats' snare is a bit crappy to my ears and to a lot of other users' ears also, but does sound okay as part of a multi-layer sound. You can create a decent snare on your Nord then augment it with the VBeats snare.
I'm sure you get the idea of how to deal with the situation from what I've suggested, so I'll leave it there.
A bit of reading about modding VBeats produces stories of incomplete circuits that require resistors added to get what is supposed to be the snare sound. It's a rather chintzy machine really only saved by it's kick and hats. And even then it is a bit of a disaster when the kick is used within it's own kit. At high instrument levels, the kick will drown out most of the other instruments. It actually sounds like there is a compressor at the end of the circuit that is set to follow the kick's dynamics. It can create some interesting pumping results similar to those Novation are touting as a feature on their Circuit (which sounds like the cheap and nasty groove box it is when sat next to analogue gear, but it's sequencer is pretty decent still).
I'm still keeping my Volca Beats, bypassing the kick issues by getting a Volca Kick (lol). I have a Vermona Kick Lancet which is nice sounding kick synth, but the VBeats' kick has some really classic elements to it's sound, like the tennis ball kick, that with a little reverb can be turned into a basketball kick.
Blah blah blah, I'm way off topic now, time to stop!
