i noticed there are two entries for the raidons in the pokedex. one for each form. by default we have the original entries, but how do we unlock the other entries? is it possible.
No, you can't unlock the Pokedex entries for Koraidon/Miraidon's ride forms. They are unused content.
The Cutting Room Floor has more info on unused content for the ride forms (and other elements of Scarlet/Violet).
