I think from the traditional imaging there is no changes, only the way in how the image is delivered to the endpoint. If the image answer file contains the domain add then that would fail as the computer can't contact the DC, but I think the use case is more for azure AD, now I have not done this personally but there should be a way.
if VPN can be configured to connect then you might be able to add the device to the domain however the GPO will not fully apply as the startup can't contact the DC.

How will joining to a domain work? Do you need change anything answer file wise? This seems like a major milestone, upgrading ourselves on the 12th but love to know more.
