Enterprise has been acquired by Mirantis in November 2019, and downloads have been removed from Docker Hub around December 2020. Also, as far as I understood from short answers after contacting Mirantis, the Mirantis offering on Windows Server only supports Windows containers, not Linux containers. Things have been rebranded to Mirantis Container Runtime (MCR).
So, short answer: see MCR on the Mirantis website.
