Property setter documentation:

Called by a device owner, profile owner of an organization-owned device, to set the Memory Tagging Extension (MTE) policy. MTE is a CPU extension that allows to protect against certain classes of security problems at a small runtime performance cost overhead.

The MTE policy can only be set to #MTE_DISABLED if called by a device owner. Otherwise a SecurityException will be thrown.

The device needs to be rebooted to apply changes to the MTE policy.
