Zoom support maintains a (non-public) list of known SDK keys for popular bots and note-taking apps and has the ability to block specific SDK keys from joining meetings on your account. This is not possible for account owners/admins to do by themselves, unfortunately (hint - give feedback on this!), but it is possible.

You will not be able to block these SDK keys for specific meetings only - it's all or nothing across your Zoom account and a lengthly change (days, not minutes, including support time) to implement in either direction.
