I see how you can set consistency to eventual on get reads off the secondaries

However, there can be replica lag so this isn't safe for most/all situations on our site. We do have specific queries we'd like to run off the secondaries (or at least it's ok if they are eventual). Is there a way to set a query to run off a replica/secondary on a per query basis? Thanks!
