Most likely no, if you're referring to that display flat flex connector.. It is driver code and some internal peripheral which operates that interface, so specialist knowledge is needed to program it to perform in some unusual manner - if it is even possible.
There are other ways of expanding GPIO on the larger 40-way header, such as using I2C or SPI to connect to an 'I/O expander' chip.
I see... Thank you for your advice～
'I/O expander' Is a good solution
