Jetson NX, USB 2.0 custom using USB2 (M.2)

Hello.
I am building custom design using Jetson Xavier NX SOM
I want to use USB2 because i need two more USB 2.0 .

Q1: Can i use USB2 as regular usb port instead of M.2 ?

Q2: If so, should i designate another vbus_det? is it possible to use the GPIO13 (SOC_GPIO54) as a vbus_det?

Thanks
