Good evening, unfortunately that's not really possible, the idea of secure folder is that it's suppose to keep your important files secure while needing those verification credentials to unlock it. You can change how you unlock secure folder from a fingerprint to just a pin if you wanted to unlock it that way by opening your settings menu> going to your "lock screen option"> "secure lock" after which you'll enter your pin or password> then in "show lockdown option" that will switch it from needing a fingerprint to a pin. Otherwise you could hide important data you have in your "My files" app in different folders in there. No passwords are required for that
