About unused USB0_OTG_ID pin

This is the question about how to use USB0_OTG_ID pin.(it is pin A36)
I’m designng custom board which can mount Jetson Tx2 like a carrier board.
This custom board will use only standard type A of USB2.0/USB3.0, thus USB0_OTG_ID pin will be unused.

I’d like to know the appropriate termination of this pin.
(connect to gnd? open? or pull up/down?)
If there are recomended or reference circuit, could you please teach me it?

Just leave it unconnected.
