GIPO extender - ESP32 Display-4.3

Hi, I have a 4.3" display, but I saw that it doesn't have the i2C port, so I don't know how to increase the GIPOs, I would need 15. I could convert the 2 GIPOs of spobibile (via code) and make them become i2C which in turn I will connect the PCF8574? Anyone have any alternatives or suggestions?
Thank you
