Sorry need some reference here....
Is OUTPUT_OPENDRAIN active LOW... with HIGH being floating?

I need to set a pin with open drain but not have a HIGH/pulled up state when not active.

exactly , you can do , fore example "wired and gates" so
but take care that the protection diode of the pin will prevent you to use voltages over 3v3 , or 5v if it is a 5v tolerant pin
