IAM Auth for BYO-Cassandra

I am referring to the helm charts docs here GitHub - temporalio/helm-charts: Temporal Helm charts for how we can connect our own Cassandra instance, which mentions that we should update the relevant values in https://github.com/temporalio/helm-charts/blob/master/values/values.cassandra.yaml. We want to use our AWS Keyspace managed Cassandra instance, which uses IAM auth for allowing our services to connect (so, doesn’t use username/password). Is that supported?

NVM - noted from these posts that Temporal is not compatible with AWS Keyspaces:
