If you want a protection order dropped you generally have to go through victim witness or ask the judge to drop it. I have had two dropped in two different states. One I had to go talk to victim witness so they could make sure I was not coerced or threatened to do it and then they went to the judge. The other one was during my divorce. Family Advocacy convinced me to get a temporary order but he honestly never got served with it and by the first hearing I asked my lawyer to ask the judge to drop it (same judge who had signed it) and he did.
The judge may not dismiss it though. It all depends on the judge. I feel as if that might answer what was intended to be asked.
