Maybe. According to the FAQ...

Will FAA discover that I have an alcohol-related MVA if I don't report
it?
Yes, FAA Form 8500-8 "Application for Airmen Medical" contains an
express consent provision which authorizes the National Driver Register
(NDR) to release information about your driving record to FAA.
Information on the NDR record will contain pointers to states that keep
a driving history on you. FAA will get these records to determine if you
have a reportable alcohol-related MVA.
