Does Salesforce help in enabling Environment Hub in a standard Dev org (specifically without an ISV partnership)? Is this even possible with dev orgs? Or only available with Enterprise or any paid version/ partnership with SF? Most of my search results in this ref mentions about DE which can be interpreted as a partner dev edition. I'm unable to locate an actual credible information in this regard.
The reason I'm looking for this information is that I'm trying to do a test set-up in my dev org to demonstrate managed package publishing mechanism at a high level.
[Note that I'm not talking about partner dev editions here. I had previously dabbled with Env Hub & Dev Mgmt Org at my previous employer but they were an ISV partner with premium support.]
