Is there any way to “un-reverb” a track?

Short answer, no.

Slightly longer answer, there are a few mentions on this forum of experimental effects that may be be able to reduce reverberation a bit. The only one that I’ve personally tried is part of a software program called “Postfish”, but it is only available as source code, not as a working program.
Adding reverb is essentially a one way process - you can add it, but it is very difficult to remove it. The difficulty in reducing reverb is why recording studios go to great lengths (and expense) to avoid too much reverb in the original recording.
