Couple of possible solutions
1) Put ignore-auto-routes=true into connection file in
/etc/NetworkManager/system-connections and restart connection/NM service.
This should reject DHCP routes, and you can add routes manually as tmp
solution.
2) nmcli con mod --temporary {interface} ipv4.never-default true
After that NM will not add default route to that int.
3) In good old days NM honored
/etc/sysconfig/network-scripts/ifcfg-interface config, and "DEFROUTE=no" in
right place meant no def route for that interface. But I am not sure if it
works nowadays, I dont use NM. More no than yes with -NM enabled.
Be careful, don't mess your network by having fun with NetworkManager and
D-Bus.
