On "old" versions you could - or at least you could not connect and it would allow to create a local account in this case. On the last one MS says you can't OOBE without the Internet, even with Pro, and at a first glance it seems you actually can't, but then you just press shift+F10, type oobe\bypassnro, and then it reboots and you actually can again. I'm not sure why they consider that it makes any sense. Probably just a motherfucker higher-up who really like dark patterns and annoying their customers^W advertising targets, so MS can resell more private informations and they get a big bonus.
