It will be possible, but enabled by default. And given how a lot of other features in Windows 10 and 11 have magically re-enabled themselves after updates it's likely the same will happen with this.

Microsoft's plan is to make it opt-out, so you should be able to disable it. And you can avoid it entirely by not using an NPU-equipped machine.

Opt-out is a terrible idea for this sort of thing -- something as intrusive and dangerous as this should absolutely be opt-in -- but at least they're planning on giving that much.

It is possible to disable it. The point of the NPU is to not disrupt the CPU/GPU but we'll see.
