I always put anti-rotation washers on the back side. If your switch
panel includes an engraved overlay, then holes in the panel for the
tab holes can go all the way through . . . and tabs on washers trimmed
to insure they are flush or under-flush to the panel surface. If your
panel plans don't include an engraved overlay, then consider a rear shim of
sheet metal drilled for the anti-rotation tabs . . . the instrument
panel surface stays clean. Again, you may have to trim the anti-rotation tabs
a bit. I would avoid any kind of gluing operation for this installation
except maybe to hold the rear shim in place . . . a couple of spots of
Sho-Goo works good.

Another way is to forget the washer and put a dab of RTV on the back/side of
the switch after it's tight.

You took the words out of my mouth. Except there's no need to hold the rear
shim in place if it serves more than one switch...it will be held and have
its own anti-rotation feature by virtue of being held by multiple switches.
See here:

Yes, those photos show the plate on the front of the panel, but it installs
on the rear:

Sorry, those are crummy photos from my old camera, but you get the point.
