Thanks for your time,I solved the problem this way:
in /etc/udev/rules.d
I created the file:
70-persistent-net.rules
with the following content:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="20:cf:30:f2:e1:ad", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
so I restarted the PC (!) and configured the network with nm-connection-editor .
I could probably use
udevadm control --reload-rules && udevadm trigger
instead of rebooting, but it doesn't seem to have worked.

I've been using the #3 scheme which is based on the geographical location of
the
network card. The system will prefer schemes #1 and #2 if the bios numbers them
but #3 always works nevertheless during installs.
