Xavier USB Design AC capacity

I want to ask where should AC capacity to be placed when design xavier carrier board? Near the SOM ( Just the SOM Connector) Or near the USB Connector?
Another question is should AC capacity be placed at both TX+/- and RX+/- line?just like P2822 doc as below. Or only required on TX+/-,like OEM design guide?

Near to USB connector and only for TX. The design you marked is for combo connector, the AC cap on RX can be 0ohm instead.
