you can set the related option bytes to avoid the boot pin impact.
you can check the Boot configuration part of the reference manual.
nBOOT0 FLASH_OPTR[27] set to 1, and nSWBOOT0 FLASH_OPTR[26] set to 0 will make the chip boot from main flash and regard less of the boot pin.

Check if there are Option Byte settings to fix nBOOT, or similar
