If your threat model includes "The government is prepared to torture me to obtain my encryption keys", it should also include "The government is prepared to lie and claim they found incriminating evidence on my device, and lock me away forever."

Just make sure that your device doesn't contain information incriminating other people who the government are trying to track down. That means not using real names, or metadata that connects pseudonyms with physical identities (e.g. phone numbers).
