I saw this post when running into the same issue.  the link below can help you use ifupdown & netools...which you already have installed (and working) and it also includes instructions for "systemd-networkd (netplan)" which is what ubuntu and debian variants of armbian appear to use.  I hope this helps you or others than come across the topic.
