Not as far as I know, but you should be able to do something similar via
a conflicts directive.

e.g. if you have NAutoVTs=6 by default you can just put:
Conflicts=autovt at tty1.service autovt at tty2.service ... autovt at tty6.service

This should prevent then kicking in. That said, I'm really not sure how
much you gain here. They are loaded on demand afterall, so it's not like
they are buring CPU cycles etc. Personally it doesn't seem worth the
bother to me, but maybe you have your reasons :)
