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.

On all 2016+ US Toyotas, removing the fuse labeled "DCM" will disable the following:

•) Wireless communications module (including OnStar and telemetrics)

•) Front passenger dashboard speaker (there is an easy bypass to re-enable, but must open dashboard — in which case just remove the entire module!)
