That's disabled unless the firmware sets up MTE and doesn't disable it for the OS. The Pixel 11 shipped with MTE hard-wired to disabled via the firmware with no way to enable it. The initial August 2026 update and the early non-QPR1 September 2026 update didn't enable it either.
Android 16 QPR2 Beta 4 was released around 2 days after we made our initial thread and added back partial firmware support for MTE. It's now possible to enable it again via a fastboot command, but not via the OS using Android Advanced Protection Mode or developer options. It's still disabled from the OS perspective but it can be forcibly used after enabling it in the firmware using ADB.
The way it shipped was that it was entirely unavailable due to the firmware not having support for setting it up for usage. It's not present in the OS in the way it is for the Pixel 8 through Pixel 10a either.
It's now usable with the Android 16 QPR2 Beta 4 firmware but it appears there's something wrong with it, otherwise it wouldn't be disabled tghis way.
