STM32F4, CubeMX, SRAM Address Remapping (FSMC_A0, A1 … An) question.

I’m working on a project were I have to connect a camera to a custom PCB and store couple of images to external SRAM (19 bits Address length).
I’m working with the STM32F407ZGTx and I use CubeMx to generate some code, and the problem is the following:

On the custom PCB the pin PD12 is connected to the camera reset pin, so I can’t use it for FSMC_A17 address, therefore is there a possibility to make PD13 = FSMC_A17 and PE3 = FSMC_A18? (the hardware was designed in thisway)

*Note: I can’t access other pins on STM32 because there are connected to other modules.

If you have any suggestions, please leave a comment.
Thank you.
