I can assure you this is not the case with all Toyota models or even most. It's often integrated into the radio instead of a separate module, or simply not on a dedicated fuse, but sometimes it is. Disabling it can also lose other features of the car such as navigation, remote start, the Bluetooth mic, or the mandatory eCall feature if you're in the EU.
No but it often involves voiding warranty and/or labor-intensive, really annoying work to access something you can disable.
On Toyotas, you simply remove a fuse [which can be re-installed].
