After assigning the network configuration abstraction renderer to NetworkManager not networkd in /etc/netplan/00-installer-config.yaml, then we do warm reboot test, some of the NIC interface lost their static ip in some reboot cycles when the rendered is NetworkManager, but networkd as a renderer is works well, all NIC interfaces can get their corresponding IP that configured in netplan confile file.
