I am looking at the same thing. Finally found some at Dell (which makes sense for us because we're using Dell hardware): https://www.dell.com/support/article/us/en/19/sln312519/intel-unite-downloads?lang=en
We have that our Enterprise server has an internal download link for our client to install unite client. We need to upgrade our Enterprise Server Installation on a new server. Looking for a reply from an Intel employee with a private link. I have to take on this project at the hospital here our last engineer moved on.
