It doesn't appear to  do so, although I haven't triggered the stability control while using ACC to test. I can see where this might be a good idea to avoid inevitable lawsuits for re-arranging someone's rear bumper due to driver being clueless about situational awareness.
If the front sensor gets covered by splashback [fairly hard to do], mud, ice, snow, it
will disable ACC and put a warning on the VIC.
