Change the start address on flash for cortex 4 core of STM32H747

Hey folks,

I am working on a project and I need more than 1 MB of flash memory for cortex 7 core on STM32H747. I know that cortex 4 core would start reading the flash from 0x08100000 (which is exactly 1 MB away from 0x08000000 of the cortex 7 core). Is there any way to change this address to something else?

Change the BOOT_CM4_ADD0 option byte in STM32CubeProgrammer.
