Keycloak-operator service annotation for SSL routes

We are using the keycloak operator (21.0.1) on an OpenShift cluster and would like to know if the keycloak operator (21 and greater) can also annotate service.alpha.openshift.io/serving-cert-secret-name when creating the service or do we have to do this manually afterwards? Annotation of the service generates a certificate from OpenShift that can be used for an encrypted connection to the Keycloak instance. We could not find anything about this in the documentation and would be grateful for any hint.

Many thanks
