for the h753 custom board- how to have additional gpios for extra sensors

Since we have decided to create the prototype, the first requirement is ensuring that the chosen H753-EVL board is functioning properly. However, its GPIOs are already occupied with essential peripherals such as LTDC, FMC-SDRAM, SRAM, NOR flash, USB_FS, USB_HS, and Ethernet. Therefore, we need an additional 25 GPIOs for the thermal printer and its motor. Should we share the SRAM and NOR flash buses with SDRAM for any specific reason? Additionally, is it possible to use a 1024x600 display with the normal DWIN GUI and later switch to TouchGFX?

where,we dont' need stlink,audio,expansion and Arduino connector too..is removing sram,norflash and using only qspi and sdram alone can give us gpios?? is that not affect any working of custom board after assembly.
