Yup. For the unaware, your phone is likely encrypted at startup, and uses your PIN/password as a key. So if you turn it off, they’ll have a hell of a time breaking into it.
At the very least, initiate an emergency mode. On iOS, this can be done by holding the lock and volume down buttons for a few seconds. It will show the “Emergency Dial” option, along with the power down option and the medical ID option. Once you have seen that screen, the phone is locked until the PIN is used. It disables all biometrics, so they can’t just use your face or thumb print to unlock it. And this makes it significantly harder for them to access your phone.

Android has an equivilent mode called “Lockdown mode”, where you activate it by holding the power button and pressing “Lockdown”.
For both devices, though, I would still recommend either shutting down or rebooting (and not unlocking) the device.
