Not as far as I know @nickmbailey, I've wanted functionality like that in the past too

yeah i just ended up manually replicating the release steps in my CI setup

Isn’t there a way to do that, not in the release tasks but in the repository setup?

Yes, there is. In github in the sample.project.clj under the :repositories key

;; Repositories named "snapshots" and "releases" automatically
;; have their :snapshots and :releases disabled as appropriate.
