    Android can disable these alerts using ADB

    adb start-server

    adb shell pm disable com.android.cellbroadcastservice

    Edit: AND

    adb shell pm disable com.google.android.cellbroadcastreceiver (This is the Wireless Emergency alert app specifically)

    Caveat:

    CellBroadcast is a feature of the Android Open Source Project that allows devices to receive and display emergency alerts from cellular networks. Learn how to implement CellBroadcast in your device, how to configure the broadcast channels and languages, and how to test the functionality with the CellBroadcast app.

    This is the app code that provides these alerts.

      Most devices just ask you if you want to keep receiving emergency alerts after the first one. (At least in Romania)

        Some countries send it on a channel level which cannot be blocked/silenced/opted out of.

        The ‘presidential alert’ level.

            If the disable method doesn’t work, you can try

            adb shell pm uninstall -user 0 -k com.android.cellbroadcastservice

            Edit: AND

            adb shell pm disable com.google.android.cellbroadcastreceiver (This is the Wireless Emergency alert app specifically)

            (I’ve also disabled and/or uninstalled and/or firewalled and/or removed ‘modify system settings’ permissions many of my carrier apps)

              Just live in a country which refuses to acknowledge cell broadcast exists, then you’ll die in peaceful silence in the next national emergency while operators take several hours to to send 11 million unicast SMS.
