There seem to be an option in Windows that let you specify you are on a metered connection. Probably one could check if the "saveData" option is selected to disable p2p.
As cloudy as Windows is, it doesn't seem to automatically detect/set that flag (and then you have the problem where people don't want to turn on datasave mode - like how I don't want iOS to only download updates over WiFi because I don't have any, I just want it to download it all over LTE), and getting all your website users to "opt in" to setting it is kind of an exercise in frustration to not automatically be using their bandwidth
