Clear Linux on cloud VM - how to and 2nd IP?

I am running Clear Linux on AWS using a cloud image. I’d like to add a 2nd private interface

Running, ip addr Need a 2nd one of these.

I noticed the networkmanager wasnt installed… then read a post saying networkmanager is not used on cloud and I should use systemd-network.

However I’m pretty confused about how to go about doing this. Any advice?

Still struggling with this. Going to keep plugging away so if anyone has any pointers, feel free to share.

Anyone have any ideas?
