Container setup: is it possible to enable tls on port 5347

I have this working setup in a test environment of which I did not yet have certificates applied, and noticed the cofo and vb connecting to the prosody task.
How do I enable tls on these connections?

                     + prosody/xmpp |                
                     |              |                
                     +--------------+                
                      5347^    ^5347                 
            +--------+    |    |    +-------------+  
            |        |    |    |    |             |

            +--------+              +-------------+

Where should I ask this? Anyone from development here?
