I saw on falloutnexus there's an esm mod for this but as I suspected, skyrim doesn't like it. Is there a console command (I looked but didn't see but may have missed) that can disable the vanity camera?
EDIT
*** SOLUTION **
I added this to the bottom of my skyrim.ini file
[Camera]
bReturnTo1stPersonFromVanity=1
bDisableAutoVanityMode=1
fAutoVanityModeDelay=600000.0
