      Description copied from interface: `InnerScoreDirectorFactory`
      Like `InnerScoreDirectorFactory.buildScoreDirector()`, but optionally disables `ConstraintMatch` tracking and look up for more performance (presuming the `ScoreDirector` implementation actually supports it to begin with).
      Parameters:
        `lookUpEnabled` - true if a `ScoreDirector` implementation should track all working objects for `ScoreDirector.lookUpWorkingObject(Object)`
        `constraintMatchEnabledPreference` - false if a `ScoreDirector` implementation should not do `ConstraintMatch` tracking even if it supports it.
      Returns:
        never null
