The simplest, most practical, way to do what you’re asking is throwing the water into a black hole, this is not easy to do from earth but is something you can do with large volumes of water if you need to (maybe the water is cursed or something?)
The second way is matter-antimatter anihilation. At the moment we are only able to create small numbers of anti-hydrogen atoms that would anihilate the hydrogen in the water molecules you supply, the issue is you’d be left with oxygen that could react with hydrogen again in the future, regenerating the water (it wouldn’t technically be the same water but it would be 8/9 the same as before by mass). So we’d have to invent anti-oxygen generation (this would be incredibly difficult) AND even if we’d succeed we wouldn’t be able to create macroscopic quantities of either because in the process of doing that we’d be creating a lot of antimatter that would anihilate matter it encounters (in our devices), if these are macroscopic quantities in a short time the outcome is effectively a nuclear explosion
