Scaling down EFS on Datomic Cloud?

TL;DR: after deleting a big database, how to scale down the EFS resources of a Datomic system?

We’ve recently deleted a Datomic Cloud - hosted database, accounting for most of our data, in order to migrate it to another store.

As expected, we’ve seen the number of stored datoms diminish drastically; however the EFS metered size has remained essentially the same, which is a problem for us as it’s a big part of our AWS. Is there a way to scale it down to the data we’re still using?
