I can't tell you about MEG, but here's a method for EEG:

We are playing around right now with questions of source localization and
whether it might be possible to clearly localize the DBS to its subcortical
source. Ask me in three months.

If you have any capacity to request things of your subjects' neurologists,
there are some papers in the literature suggesting that artifact is weaker
in a bipolar configuration compared to  monopolar. Again, EEG only. Here at
Martinos the only recommendation I've heard about DBS+MEG is "doesn't work
well". I don't know of anyone who's really studied the problem.
