Removing specific database from the update task

I know in Domino 8.5 there is a new feature that allows for the removal of specific databases from the update task. Does anyone know how to do this? Thanks!

Subject: Are you thinking of “On Demand Collations”?

Which are configured for each sort column in designer and when enabled keep the update task from doing the work to keep that view index up-to-date as changes are made to the database in question… Will significantly reduce the amount of CPU the update tasks uses…
