     * The configurations for nRF54L-based board targets that store the MCUboot verification key in the KMU peripheral to automatically generate the :file:`keyfile.json` file in the build directory (the ``SB_CONFIG_MCUBOOT_GENERATE_DEFAULT_KMU_KEYFILE`` Kconfig option) based on the input file provided by the ``SB_CONFIG_BOOT_SIGNATURE_KEY_FILE`` Kconfig option.

       The provisioning is only performed if the ``west flash`` command is executed with the ``--erase``  or ``--recover`` flag.
