Nighthawk (R6700v2) setting to limit bandwidth on individual devices?

[PNW_Guy]

Hello; for my model described, is there a setting where I can limit the monthly download (say, 200GB) on a specific connected device? I looked through the settings and can’t find anything.

The reason I’m even interested in doing this is because Xfinity states I went over my monthly limit, which I’ve never done before, so trying to narrow down which device is the culprit…

Thanks!

Clarification: I’m looking for a setting to use on the Nighthawk Netgear iOS app
