Certainly:
 
  rndc freeze [zone]
  [edit the zone file]
  rndc thaw [zone]

That's assuming you are at BIND 9.3 or later. If you aren't, you should be.

But why do you say that you can't remove NS records with nsupdate? I have
done that lots of times. There is one gotcha: you can't remove *all* the
*apex* NS records for a zone: BIND silently retains the last one. The solution
is to add the new NS records, then delete the old ones, in the same update
transaction.
