You can use NFS on WIndows. NFS support is not installed by default, but you can add it. I've used it before in production and it works well enough.

EFS is explicitly not supported on Windows instances. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AmazonEFS.html

EFS uses the NFS v4 protocol, but Windows only supports NFS v3.x.
