Yeah, like you could have a seed phrase written down and stored in a safe. It may or may not have funds on it. It's a decoy that you can give up while appearing to comply with an attacker.

Similarly, you can set up a duress wallet on some hardware wallets. You would have a normal PIN, and a duress PIN that, when entered, accesses a different seed that you can have funds on to fool an attacker. You would have to determine how much to put into the duress wallet to give it an appearance of authenticity, enough to appease an attacker and make them go away none the wiser.
