Keycloak Infinispan Custom Storage Class

Hi,
I’m using KC18, is it possible to use an infinispan custom storage class to persist cache in somewhere instead file?

here is the infinispan schema
https://docs.jboss.org/infinispan/13.0/configdocs/infinispan-config-13.0.html#
infinispan → cache-container → distributed-cache → persistence → store
