A free mod for Mount & Blade II: Bannerlord, by Pyrolyzed.

Take Both is a game mod for Mount & Blade II: Bannerlord that allows you to get two perks at once instead of having to choose just one. You don’t have to decide which perk you want, just take both! If you’re like me and have a hard time picking, this mod removes the choice altogether!

Take both the perks will automatically be added to your character when you load a save game or create a hero. It’s also compatible with older save games, when you load a save and when a hero is created, the game will add all previously taken perks alternative to all heroes (or the hero that was created).
