Any Information on P2 to connect something? #21

I can see next to the usb C port there's place for a 4 pin connector labeled P2. I was hoping we could use this to connect something like a buzzer.

I found in the schematics this P2 connector is for SWD debugging. But I have still wonder I could use these 2 pins as GPIO pins. Is there any risk or considerations to make?
