Unable to remove default route

Hello,

How can I remove the default route when my Beaglebone Black is connected to the Ethernet? I tried sudo ip route del default command, but connman adds the default route back…

Nov 15 13:48:30 evolve-1 connmand[590]: eth0 {del} route 0.0.0.0 gw 192.168.1.1 scope 0 <UNIVERSE>
Nov 15 13:48:30 evolve-1 connmand[590]: eth0 {add} route 0.0.0.0 gw 192.168.1.1 scope 0 <UNIVERSE>

Is the only way to disable connman service?
