In iOS 11 and higher, you can disable Touch ID by pressing the power button 5 times in quick succession:

> In iOS 11, Apple has added an "Emergency SOS" feature that's designed to give users a quick and easy way to summon emergency services should the need arise. As it turns out, there's a secondary benefit to Emergency SOS - it's also a way to quickly and discreetly disable Touch ID. ... This is a handy hidden feature because it allows Touch ID to be disabled discreetly in situations where someone might be able to force a phone to be unlocked with a fingerprint, such as a robbery or an arrest. With Touch ID disabled in this way, there is no way to physically unlock an iPhone with a finger without the device's passcode.

"Pressing power button 5 times in quick succession" doesn't work on my iPhone 8 Plus running iOS 12. To achieve the same effect, I need to hold the power button and one of the volume buttons for a couple of seconds.

Sorry - looks like the power button x5 trick only works on iPhone 7 and earlier (had tested successfully on a 6S before posting): https://support.apple.com/en-us/HT208076

> "summon emergency services should the need arise"

What does that mean? It calls 911 or the local equivalent? That doesn't seem like desired behavior if you're triggering it in anticipation of crossing a border.

There's a slider to call 911/emergency services (as well as to show medical ID). You can configure it to call 911 after 3/5 seconds but even then there's the second countdown with a cancel button. It prevents biometric unlock either way.
