Set backup Retention Count on Controller for Collect Backup Agent Task

I am using Ignition 8.1.15 for a project with multiple gateways controlled by the Enterprise Administration Module. Is there a way to set a retention count for how many backups of each agent will be saved similar to the way a local gateway can be set in the Schedule Backup Settings?

I'm looking for this

to exist somewhere here

It looks like retention policy for EAM backup tasks was introduced with Ignition 8.1.19:

EAM Controller now implements an optional maximum retention policy for agent gateway backups. Older gateway backups will be automatically deleted when the max retention age is exceeded. A maximum number of retained gateway backups can also be specified.
