Hello! How to use ros in xavier agx to communicate with the built-in CAN?

Hi @18272077327, first it is recommended to confirm/verify that you get CAN bus working on your Jetson AGX Xavier:

https://elinux.org/Jetson/AGX_Xavier_CAN

The can-utils and cansend/candump commands from that page uses SocketCAN. It looks like the ROS_CANOpen package also uses SocketCAN, so you can try that ROS package next.
