How to get Koraidon in Violet without trading?

Hello there, fellow Pokemon fan! I'm curious to know, how exactly can one acquire the legendary Koraidon in the game Pokemon Scarlet and Violet without engaging in any trading activities? I've heard that the game's story usually involves obtaining the version-exclusive legendary Pokemon through a trade, but is there a way to bypass this and still add Koraidon to my Violet team? Perhaps there's a secret quest or a hidden location where it can be found? I'm eager to learn the details, so if you have any insights, please do share!
