I'm in Canada, iirc I can toggle something on my phone that says "don't show alerts" but it does nothing, at least for various broad categories we can't turn it off. There are regular articles admonishing people for complaining about getting 3AM amber alerts from 100s of kilometers away, as if we should all be doing our part waking up and checking our house to see if the suspect and child are there.
