Question

Can I set the MPU to prevent any further modification of the MPU settings?

Answer

No,

The ARM v7-M Architecture Reference Manual shows that access to the Private Peripheral Bus region of the memory map always uses the default memory map settings irrespective of whether an MPU is present and enabled.
