Ok, so how do I tame that?
That's the problem, the guitar is just being what it is, which is the sum total of it's parts and construction. It's not a single thing that has cause and effect. You can't unmake it and put it back together without the resonance.
The things you can consider are things that you can change. Like trying different types/makes/guages of string. You might want to see if you can work out a fretting technique that minimises the buzz. You could try a combination of the two.
Alternatively you could decide to live with it, or you could shop around and find a new guitar and fund it by selling this one.
It all comes down to how much time, effort, and expense you are prepared to go to in your efforts. But with no guarantees you will find a suitable compromise.
Sorry I can't offer anything beyond pragmatic advice.
