You've already gone online with your console so restoring your backup would actually make matters worse because you would be reverting your console to a state that doesn't match what Nintendo has on their side. At this point, there is no point crying over split milk and what's done is done. You've already been flagged and you cannot do anything to reduce your chances since the information has already been transmitted to Nintendo. All you can do is just be careful to not send any more telemetry to Nintendo.
While I personally haven't played the Switch version, from what I've seen & heard, its more like a port with quality of life improvements. Meaning its pretty faithful to the original both gameplay-wise and graphically.
