There is a relationship where systemd-networkd can feed dns information to system-resolved that could be helpful in dynamic IP configurations like laptops. However this is not usual case in AWS deployments. The Debian AWS AMI does not use the usual NetworkManager configuration because the usual AWS deployment does not required dynamic  DNS. In my AWS deployments I remove systemd-resolved and use bind9 instead.
