Counter: the border agent asks "are you hiding any information from us?". answer yes, and they get you to disable travel mode. answer no, and you just committed a felony.
As a general comment to so many of the follow-ups to this post: You really, really don't want to get into a rules-lawyering match with Federal fucking prosecutors over whether "clever technological solution" counts as "hiding" something or not. They have all of the guns in this situation, and you have a demonstrably inaccurate understanding of the relevant statute. You WILL lose.
Your adversary here is a group of humans. Not a Bash script.
