Anyway to check if a Nintendo Switch's game codes have been used or not?

Posted 11th Nov 2021
Hello I have a Nintendo Switch game to give to a friend, it isn't sealed but there are 2 DLC codes inside on a card. Can I check if they are unused without actually redeeming them? I know you can do this with PS4 games but I am new to the Switch and don't want to redeem the code just check
