TPS65982DMC: TBT4 device based on Gorilla Creek TI88's TPS65982DMC issue

Part Number: TPS65982DMC

Hi  TI engineer

I am developing a TBT4 device based on Gorilla Creek TI88. I found that the GPIO_1 pin of the TPS65982DMC is connected to a USB current detection chip (as shown in the attached image). I do not see this pin used in the firmware configuration tool, can I leave this pin suspended? Or does it need to be set in the firmware?
