The iPhone has never had such a feature _exactly_.

However on iPhones that have the Emergency SOS feature biometry is disabled until you enter your passphrase/code when that feature is invoked.

Biometry is also disabled until re-authentication if you invoke the shutdown menu by holding the power/power+volume up button.

Neither of those will get you to the Before First Unlock state, however. That is the ideal if you are attempting to protect access to your phone’s data in any adversarial scenario. You must restart/shut down the phone to get back to that.

Same applies to iPads.

There may be vulnerabilities, of course. In Before First Unlock there is not enough cryptographic material available in memory to decrypt application data. The full set of keying material is both user and device specific.
