Considering SCA is based on the WildFly AS, it's not excluded it could be possible but it needs to have some knowledge of JBoss/WildFly architecture or any networking to mask IP/hostname.
The Support have seen some customers doing a redirection for calls from external/internal sites switching from HTTP to HTTPS and vice-versa behind a firewall through a Load Balancer software like F5. Of course, this way doesn't hide the hostname URL where the SCA is installed but they rename the hostname URL over the redirection call.
As said, to do this it is needed to have knowledge of networking and Wildfly AS structure and it is out of SCA configuration.
