In kingdom hearts 2 final mix can you get your third finisher plus in standard or beginner mode?

In Kingdom Hearts 2 Final Mix, you can obtain the third Finisher Plus ability only in Proud and Critical modes. In Standard and Beginner modes, the ability is not available, as these modes have a different ability progression system that limits the acquisition of certain skills. Therefore, if you want to unlock the third Finisher Plus, you would need to play on a higher difficulty setting.
