Hi!
unfortunately not. I have the same issue. You can create Port-Channels itself, but command is not available under interface commands.
I dont know why they they disabled it, it is just a software limititation I guess.
C892-(config-if)#int port-channel 10
C892-(config-if)#exit
C892-(config)#int gigabitEthernet 1
C892-(config-if)#channel-group ?
% Unrecognized command
