Azure Files: SMB over Quic - support for DFS-N

Question

Reading up on SMB over Quic to be used with Azure files and wondering how this would integrate with DFS-N in a work from home.

Reading a blog with the following statement:"Since the client cannot reach a Key Distribution Center (KDC) over the internet, Kerberos is not an option, as there is no direct line of sight to a domain controller." would this then also not apply for a remote hosted DFS-N setup? Meaning that DFS-N with SMB over Quic would not work unless you had some kind of VPN to a network hosting the DFS-N service but that would be a complex setup.

Is this not documented because it is obvious or is it me not understanding how SMB over Quic would work in such a setup?
