Is it possible to modify this register field using STM32CubeProgrammer?
I've tried both:
But neither work.

The BOOT_ADD0 option byte can be modified from within the option bytes editor in STM32CubeProgrammer. The "OB" icon on the left.

Option bytes ultimately reside in non-user FLASH and need to be applied by setting OBL_LAUNCH and letting the chip reset. This is what "Apply" does in the option bytes area.

That's what I thought too, but I don't see that in the option bytes section.

Just in case others see this, looks like your chip doesn't have a BOOT_ADD0 option byte. Is there a reason you think it should? The BOOT_CM7_ADD0 is what you want to change.
It does appear that the H743 reference manual suggests BOOT_ADD0 exists.
Put your chip number in your post so others don't have to guess what you're using.
