How to configure Secure Connection for External Cassandra & Cassandra as a Database connection

While configuring Connect-Cassandra, we have option to choose Secure connection and provide Keystore details (see attached). Similar how can we set Secure Connection for DDS External Cassandra (we are using an enterprise shared datastax) and also how can we set Secure Connection when creating Database instance to a different keyspace in same Cassandra instance?
