MCUboot placed to immutable flash #nrf52840 #dts #crypto

Hello, I am studying this which mentions that the MCUboot is placed to immutable section of flash. How is this implemented? I can not see anywhere information about immutable MCUboot partition.

In general, that's left as an exercise for the user, as far as I know.
