CG-NAT is inside of your ISP network and generally won't affect outbound connectivity to the internet at their customer side. Generally any devices capable handling NAT wouldn't have any problem connecting to CG-NAT based ISP networks.

    Just treat as any other internet circuits when you configure it as a member of SD-WAN zone. If DHCP or PPPoE configure it accordingly.
