Cannot find device "can1" error in avermedia nx215 with nvidia xavier nx module

when i normally initalize the can1 on my avermedia nx215 board with xavier nx module, it is showing Cannot find device “can1”

For can1 to be available, the pin mux needs to be enabled, the kernel modules need to be loaded, and the interface needs to be configured with ifconfig or ip link.
There are a couple of good answers about this over on the Xavier forums.
