I’m not sure what this post is about … but answering to the title, the correct way of making changes on network connections on Enterprise Linux systems is using nmcli.
The command is like follows:

# nmcli connection modify "connection name" 802-3-ethernet.mtu "mtu_value"

Which for connection eth1 for example would be:

nmcli con mod eth1 802-3-ethernet.mtu 1450
