Network Configuration in NVIDIA Filesystems

The service/daemon that manages/configures the network in NVIDIA filesystems (driveos-core-rfs, driveos-oobe-rfs, driveos-oobe-desktop-rfs) is systemd-networkd, which is different from the standard network manager (NetworkManager) used in Ubuntu 20.04 by default.

systemd-networkd is the only network manager installed. Hence, utilities like netplan aren't installed to support both systemd-networkd and NetworkManager.
