Can u check and see if the rear back up camera in the Ford emblem is bad without breaking the plastic tabs that hold in the camera and emblem?

Internet claims to even check if a wire came
off the rear back up camera is bad that you
have to remove the emblem and it states
that cannot be done without breaking the
plastic anchors and having to replace the
emblem.  Took it to a  Ford service center
and they quoted a 489.00 replacement and
said the camera is bad yet the rear
camera/and emblem is still on without
looking line it has been touched.  Want to
know if it's possible before I go confront the
service shop.  Thank you.
