The preferences that are related to biometric settings should only be searchable if the device supports the multiple biometric auth. However we can see these preferences still can be searched even the device doesn't support the feature, which is caused by that there's no guardence. So the availiability of the preferences need to be updated to prevent revealing unsupported preference from Settings search. Fixes: 187167774 Test: manual test 1) Navigate to Settings search on a device without face auth 2) Search for face 3) See if there's something about face unlock Change-Id: I6f120e8d9002a1e8f0be9361fdbea193776e4d7d
