I just tried this and it seemed to work to keep Face Refinement from recognizing a face that it had no problem with. (Sort of the opposite of your problem, but I think applicable.)
I created a Correction node before the Correction node onto which I'd dragged the Face Refinement. (I assume it works the same if you drag Face Refinement directly, but I always drag onto a Correction node.)
Then I created a Power Window, inverted it and used the color wheels to take everything outside of the Power Window to black. When the Power Widow was off of the face, Face Refinement did not find it, and when it was on the face -- or if there were no initial node at all -- it found the face.
So I assume you could create a Correction before, Power Window -- and track if necessary -- over the face, and bring the rest of the image besides the face to black. In a harder case, do an Inside to make the face more face-ish -- think like an algorithm -- and then an Outside to blacken everything else.
I remember the tip -- but had to work out the details -- from one of Darren Mostyn's Youtube videos.
