@Kisa0 anyone who has read my listing will notice that I have a pretty firm stance on rules (and frankly, I think all hosts should make careful work of listing their House Rules!), but in this case if you want to enforce a No Alcohol policy (in an entire place) then you'll need to list that more often and more prominently than just tucking it into the other things to note section. I'd suggest: in the listing text, in a photo text, in the House Rules, in the House Manual, in the other things to note and in your first message confirming a new booking (if you're IB or during the pre-booking discussion if not on IB).
The reason why I think it requires so much repetition is bc most people would NEVER imagine that a host would be telling them what they could consume in a self-contained entire listing.
People do expect that a host might concern themselves with: unlawful behavior (drugs or drunkness, human trafficking, prostitution, internet torrenting, etc), cleanliness, safety, smoking, proper guest count and several others...
But trying to control for all sinful behaviors is a futile effort. There are many sinful behaviors that guests can engage in while they're in your space: they could lie, gossip, argue, act with malice, curse, be dirty, lust, overeat, dishonor their parents.... we could go on and on. The advice I've given other friends who are concerned with guest behavior somehow sullying their home with their bad behavior is that likely they aren't a good fit for a STR platform. If your conscience troubles you that guests could behave badly in your home then that is an intractable problem.
But if the only thing that bothers you is alcohol then you could try to proceed, I just don't know that it will be easy. So, just keep in mind that this restriction is outside the norm (well outside) so I think you'll need to really drive the point home.
Good luck.
