Lock down the client
Is it possible to lock down the NextDNS client to prevent the user meddling with it? My client is using NextDNS in a classroom setting and we don't want the students meddling. They can disable NextDNS and/or quit the client:
They can also meddle with the settings. It's not critical because if they do stop NextDNS working and it falls back to the router, that has NextDNS on their as well.
Would kind of prefer it to run as a service so a non-admin can't change the settings.
