ENA was part of why we went to maintaining our own AMIs: if you enable in the AMI, you don't have to worry about enabling it in the resultant EC2s (plus, if you're using a non-ENA AMI to build ENA-enabled EC2s from, it makes for a really annoying provisioning-process (create EC2 from AMI → stop EC2 → modify EC2 → restart EC2).

Thanks Thomas for the info. Frankly, I didn't know that ENA can be enabled in AMI as well 😅😀

Two key arguements to aws ec2 register-image when you want AMIs with high-speed networking:
--ena-support
--sriov-net-support simple
