Is it possible to expose TCP Openshift Service using routes with SNI?

Is it possible to expose TCP Openshift Service using routes with SNI? I am trying to have a TCP service in Openshift be exposed to outside the cluster with SNI. This article goes through some general idea of it. https://blog.zhaw.ch/icclab/openshift-custom-router-with-tcpsni-support/

Unfortunately, I am not able to get this working at the moment and the article is dated so I am not sure if it is the best resource to use at the moment. Does anyone have any other resources?

NodePort Service is the way when an application needs to expose TCP protocol outside OpenShift cluster.

Here is the limitation of the Ingress Controller (Router) *1

This is limited to HTTP, HTTPS using SNI, and TLS using SNI, which is sufficient for web applications and services that work over TLS with SNI.
