Is it possible to debunk Intel Management Engine conspiracy theories using a data usage monitor device?

If there would be any backdoor in recent Intel CPU's, then it should send and receive data secretly. Isn't it possible to easily debunk this conspiracy theory by implementing a third physical device between the computer and the router to find out if…
