Why do you want this feature?
When using a node group spanning multiple availability zones and using cluster autoscaler, there can be problems due to a native ASG process rebalancing nodes between AZ. AWS provides a way to suspend this process called AZRebalance.
What feature/behavior/change do you want?
I'd like a way to provide a list of ASG processes to suspend when creating a node group. For example, here is how kops does it.

We just migrated to EKS from kops and are missing this functionality. It would be great if this functionality was added since we now have to manually update the auto scaling group's every time we create a new nodegroup.

Same here. But we understand it is better not to span a single ASG on several AZ.

Hi, I believe that this should be reopened, as the changes in #2487 don't seem to work. The AZRebalance process is suspended only while cloudformation is updating the ASG. I don't think that ever happens in the eksctl workflows, as they are immutable. Regardless, that doesn't solve the problem in this issue.
