Is it possible to use plugins if I have Illustrator from M0nkrus or Genp?

Note: I am not requesting a link, source, nor a how-to, but rather I am curious if it is possible to use plugins if I have Illustrator from M0nkrus or Genp, because then I will know that continuing to search for one won’t be in vain, and that I am not just being foolishly optimistic.

Thank you.
