EKS Workshop : Some Instances are not supported in US-WEST-2

[4pits]

Some Instances are not supported in US-WEST-2 ( us-west-2d zone)
Should we remove the instance types(m4.xlarge) from create nodegroup command or we ask users to only use us-west-2a, us-west-2b, us-west-2c.
It can vary based on account to account, but still in unsupervised cases its good that the creation of node-groups runs without an issue
