You can trigger Emergency SOS (aka "cop mode" - either to call them or to avoid them, tbh) by pressing the power button five times on iPhone 7 and below or holding side button + a volume button on iPhone 8 and up. Dismiss the prompt to call 911, and then your phone will be in a state where Touch ID / Face ID is disabled until you successfully use your passcode again.
It appears Wallet still works so you should still be able to get to boarding passes without unlocking the device.
Is it going to be a manual disable?
