Hi,
this can be done via the web UI. Go to Compute -> Hosts. Here click on the
name of host you want to configure bond on. Then Network Interfaces ->
Setup Host Networks. Here you should see your bond, by clicking on the
pencil you should be able change the bond mode.

Hopefully this helps.

Regards,
Ales.
