Jetson Nano + 2xarducam_64mp + libcamera?

Hi,

do the same arducam_64mp cameras that i use on raspberry pi work on Jetson Nano?
can i use libcamera or do i have to use some other library?
can somebody here run “sudo cat /proc/meminfo | grep Cma” on their nano?
i would like to know how much CMA they have available
