Looks like there is no support for OC.
If you want to create your own OC pins, then the simplest way is to add a FET to that pin.
A good example is in the level shifters that are used to convert 3.3V to 5V.
The 5V side is open drain. The 3.3V side can connect to a push-pull IO.

The circuits used for PS2 keyboard connector will do the task.
