How do you configure the SQL Server Network Configuration protocols in a MSSQL Express Docker container on a Linux server?

Question

The gist of the issue is that I am trying to connect to a MSSQL Express Docker container, living on a RHEL 7 server from my local Windows 10 machine using Microsoft SQL Server Management Studio. It is successfully connecting to the RHEL 7 server IP address and port (1433), using the username/password that was created for the container. However, it is throwing out an error that, after countless hours scouring Google, people have referenced back to needing to enable TCP/IP. This is easy in the Windows GUI. Not so much in a Linux environment.

The error message from SSMS:

A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (Microsoft SQL Server, Error: 64) -> The specified network name is no longer available

I know how to do this in the Windows environment:

1. Run SQL Server Configuration Manager
2. Expand SQL Server Network Configuration
3. Select Properties for Protocols for MSSQLSERVER
4. Enable TCP/IP

I have also figured out how to use mssql-conf to modify various attributes in mssql.conf, which is where this change will take place. The issue is that I want to enable TCP/IP, but I am not seeing that option under the /opt/mssql/bin/mssql-conf list | more.

Any suggestions?

For reference, these are the parameters you can use with mssql-conf (the equivalent of SQL Server Configuration Manager on Linux).

Also for reference, this is the only thing in the mssql.conf file. If something is there be default, I have no way of knowing it, because all I have to go off of is what's listed in this file:
