Answer 1

There seems to be no override or "whitelist" or policy that allows even a device owner to override this message.

Here's the code that shows the toast: http://androidxref.com/6.0.1_r10/xref/frameworks/base/services/core/java/com/android/server/am/LockTaskNotify.java#74.

Here's the code that calls this show method when a locked task is shown: http://androidxref.com/6.0.1_r10/xref/frameworks/base/services/core/java/com/android/server/am/ActivityStackSupervisor.java#3919.

There are no flags or resources that can be overridden here as far as I have found. If you have access to source, you will need to comment out the line that invokes show.
