Hi Mayue,
You can take a look at the pin diagram in PSoC Creator. All the blue pins can be modified. You can set VBUS_DISCHARGE_P1 function to other pin and assign new function to Pin 2[5].

Hi Mayue,
You can refer to the Pinouts of CCG4 datasheet:
https://www.cypress.com/documentation/datasheets/ez-pd-ccg4-datasheet-usb-type-c-port-controller
All the pins in VBUS Control, VCONN Control, Overvoltage Protection (OVP) and GPIOs and Serial Interfaces can be configured as common GPIO. And their function in default firmware are listed in Description column.

Hi Eddie
Thank you for support! I'm going to use PIN20 VBUS_DISCHARGE_P1 as a GPIO. I want to know if it can do and If it has interrupt function? Who will control 6 PINs of VBUS control ? How do they work? May I change their function?
Thanks and Best regards
