You're looking for nmtui. I went through this pain recently, so I'll 
share a few things you're going to want to know about the firewall & 
network manager.

Configure the firewall with firewalld-cmd.

Don't use --permanent with firewalld-cmd, instead do all of your changes 
then run:

    firewalld-cmd --runtime-to-permanent

Even though firewalld-cmd seems to allow you to change the zones of 
interfaces, it doesn't work like you'd think it does by reading the 
documentation. Instead, use:

    nmcli con modify ens224 connection.zone trusted

Adjusting your ens224 and zone as necessary, of course. This is the only 
way I've identified which will consistently and permanently change the 
connection zone.

If yum updates network manager or firewalld, you need to reload the 
services for the tools to work correctly; especially after a fresh install!

    systemctl daemon --reload

This will reload all the daemons.
