You can display the Flarm targets on the Oudie, but you probably want to have another dedicated Flarm display. The Flarm targets on the Oudie are good for situational awareness, but a dedicated Flarm display will be much better for the collision warnings.

If you have panel space, a Flarmview or Butterfly display will do the job. If your panel space is limited, the V7 vario connected to the Flarm and Oudie will give you a superb vario that also doubles as a flarm collision clock display.
