How delete port Channel interface on Dell N3024

Hi all,

We are using Dell N3024 model, from the configuration we created LACP but we no longer use it any more

interface port-channel 2

switchport mode trunk
switchport trunk allowed vlan 193
exit

so i expect to tidy up the configuration, but  when i run " no interface port-channel 2", the error message come up

(config)#no interface port-channel 2

^
% Invalid input detected at '^' marker.

Do you have any view for deleting the port-channel interface on Dell ? 

Thanks very much
