Not really, no. If you had a proper SAN, you could use heuristics with
qdisk, but as I said, that's not safe on DRBD.

If you really wanted to, you could modify the obliterate-peer.sh to do a
ping and only proceed if it resolves, which would help, but even then it
isn't reliable if your ping goes over a different network. You would
have to make sure that the target was on the same subnet as the
storage/DRBD interface.
