If you’re a member of a group that frequently gets added to a lot of Conversations or a collection that spawns a lot of Conversations that you don't care about, you can remove yourself from the group or collection. However, do so only after careful consideration. Once you're outside the group or collection, you can be added back in only by someone on the inside, and you may miss out on valuable information in the meantime. A better alternative is to simply mute the Conversations you don't want to keep track of. By default those Conversations will no longer appear in your Conversations list, although you can see them at any time by applying the Muted filter. (And if you're flagged in a Conversation that you've muted, you'll still be notified.)
