You can! It’s not necessarily as foolproof with the Additional Tags as it is with fandoms, characters, or relationships, as there are ways to be a bit more thorough with those, but you can do at least a pretty decent job by doing this in the filters from your pairing’s page:
Not foolproof because it’s a straight string search, so if someone’s tagged with a synonym of the tag, like “Omegaverse”, instead of with the canonical, then it won’t remove the work in question, but it should at least get rid of most of them.
(Also! You can get more filtering tips over at filter-me-ao3. It’s unofficial, but I run it, so you get the same brand of what I distinctly hope is helpfulness.)
