networking – ubuntu 18.04 ISO – Disable Network Configuration Prompts / Dialog via preseed config

During ubuntu iso 18.04 server install the network configuration manager dialog will showing if ethernet is not active.

Note: I have created unattended ubuntu 18.04 offline iso. hence I don’t want to show manual interaction like showing network configuration dialog. is there any way to disable the dialog since it has manually interacted?

Can we do it preseed file?

kindly help with this

Thanks,
Ramesh
