Cannot delete Virtual Ethernet

[kamzata]

Fiddling with /etc/network/interfaces I found out either Proxmox or Debian has created a new Virtual Ethernet named enp0s20f0u8u3c2. Now I want to delete it. I tried using Proxmox GUI and press Delete button but nothing happened. I also tried to execute ip link delete enp0s20f0u8u3c2 but the answered has been RTNETLINK answers: Operation not supported.

root@mysrv:~# systemctl | grep enp0*
sys-devices-pci0000:00-0000:00:14.0-usb1-1\x2d8-1\x2d8.3-1\x2d8.3:2.0-net-enp0s20f0u8u3c2.device                 loaded active     plugged   Virtual_Ethernet
sys-subsystem-net-devices-enp0s20f0u8u3c2.device                                                                 loaded active     plugged   Virtual_Ethernet

How can I delete it?

That's not a virtual device, that's an USB Ethernet dongle... Remove it (physically) and it'll go away..
