    The in-chip bootloader is in ROM and cannot be changed. You may look into https://github.com/STMicroelectronics/stm32-mw-openbl for a SW based solution.

    You can code your own software to do whatever you want

    The front flash sectors are 16KB to accommodate you creating you own loader/startup methods.
