How to have Keycloak operator working with an external Oracle 19 database?

I have several projects where Openshift installations of keycloak should be connected with oracle database.
We have solved that for many years using the template mechanism, but it seems to be really hard to be done using keycloak operator’s instances.
Do someone in the group have a clue on this?
Best regards

Hello, the Operator currently supports only Postgres.
