In my country police are known to torture people until they sign a confession written by them. So I don't think disabling biometrics will make a difference. But I've still done it.

Yes it absolutely is.

Every nation has a byzantine system of laws and codes enumerating different ways for police to violate the “rights” that nation has enshrined in law.

One way to avoid compelled speech (a “right” Americans have but other nations citizens might not) is to simply misremember your lock code as many times as it takes to trigger factory reset.

Americans don’t need to know that because they can’t be compelled to enter a passkey, but people in countries with no qualms about compelled speech like Germany would be well served by disabling biometrics so they have the option of lying and taking that hit instead of giving up their privacy.

Do your own research about your jurisdiction, but go ahead and turn off biometrics because it literally makes any group that can control your movement (which in English common law is the basis for the concept of “arrest”, and so likely a situation many different nationalities will face) access to your devices.
