How to remove and Update Schemas in Iglu Server

Sorry for disturbing again @josh , one fast question, is there any way to reduce the amount of time that the Snowplow Enricher service maintains the Schemas in its Cache? some magic parameter like:

"patchesAllowed": true

Based on this Post:

The cache will live as long as that Stream Enrich app instance is not terminated and restarted (e.g. by a server reboot)
