There's really no way to do this b/c of how closely the games are coupled. E.g., you'll still have Idlers join your clan, Idle content show up in raffles.
If you want to do this to prevent yourself from getting tempted by the dopamine hit promise of Idle, you can do so at the client level by blocking Idle assets and making Idle unplayable on your device. Alternatively you can buy a Pavlok and have it shock you if it sees above a certain amount of network traffic between your devices and Warzone Idle. A quick-and-dirty fix, if you want to keep yourself from getting sucked into Idle, is to just hire someone to check your Warzone profile from time to time and cause you physical pain or inconvenience if they see any new Idle achievements on it or indications that you've been playing Idle. I have this set up with my go-to fixer and would be willing to help you arrange this last option for a small fee and some information about your tolerance for blunt force trauma.
There's no realistic chance of this ever getting responded to, so I think you should look into more pragmatic client-side approaches depending on why you want to do this.

Unfortunately you are far more likely to get sucked into idle seeing as how 83% of players that avoid idle on mobile end up playing it eventually, 79% of those players also end up playing it more than Warzone Classic, and 18% of those players never play Classic again.
But if you think you belong to the 17% of Warzone players that mean it when they say they’ll never play Idle. Then God bless you, and hope you’re not also apart of the 65% of players (of that initial 17%) that attempt to remove Idle from their app and end up trapped in a virtual world.

Ooh it'd be fun to get those actual numbers although it's slightly painful to figure out who's an Idler based on public information alone. But this is a good opportunity to figure out how to classify player types with reasonable precision and recall. Anyone wanna help? Ping me on Discord and we can find a non-ToS-violating way to do this later today.
Rick, for the client-side blocking, you will have to either mess with your router or potentially root your phone. Or get a cold turkey kind of app, but that would most likely mess with WZC play too.
