Ethernet not working: "Device not managed"

Ethernet is not working on my laptop. In network manager under Ethernet it show device not managed. I have followed several troubleshooting articles but nothing worked. It is a xps 13 9380. WiFi works fine and Ethernet works on other Linux distros. I am using the 5.8 kernel in dom0 and 4.xx In net-vm. Any help appreciated.

Any help?
