Can you elaborate what you mean with Nintendo switch sync? I have switch online so I have the cloud backups between my switch and switch 2, but there are some games like the Pokemon games that don’t support cloud backups

Not to be pedantic, but you mean TP-Link (Kasa) smart lights right? I have these but haven’t bothered to block any sort of telemetry with my adguard home server. I see several domains queried that match .tplink.com but I wouldn’t want to reduce functionality as you mentioned
