Unable to create EKS cluster on AWS outposts

I am trying to create EKS cluster on AWS Outposts using Terraform AWS Provider but it is failing with error message- Outpost subnet can not be used. Please help.

Looks like aws_eks_node_group resource creates only managed nodegroup whereas AWS Outposts supports only self managed nodegroup. Hence we need way to specify node group type and also feature to create self managed node groups.
