Private Server Passwords

[Thunder1723]

Is your feature request related to a problem? Please describe.
I'm looking to see if there is anyway for me to use this to make a private server. I can see how people normally do it but I'm not too certain with what to do in my compose file in portainer.

Describe the solution you'd like
Environment variable(s) for a private server something like:

RUST_PRIVATE_SERVER: 1/0 for true or false
RUST_PRIVATE_SERVER_PASSWORD: "string"
