Hello , is it possible to capture VM physical disk placement information which is on the VM monitoring tab on vCenter UI with powercli ?
Have you tried looking at the Powercli module for VMC on AWS?

Unfortunately, I cannot verify if it can pull the details you are asking as I do not have access to a VMC cluster. Try it if you do.
