[44net] US encryption question over IPv6 transport

So, I know 44 traffic over wireless has to be unencrypted, however can 44 traffic run over encrypted wireless site to site IPv6 network. I have access to IPv6 rural Internet wireless provider commercial network, besides fiber to their sites they also have P2P wireless links. They encrypt their P2P traffic, they run VXLAN over these paths and said they could provide a VLAN where they share an RF site with an amateur repeater. Thanks Liz KI5PGJ
