The same way you can just not build the telemetry part, there should be a build flag so that users can choose not to compile the AI parts of Firefox.
This is ESSENTIAL from a security standpoint, it massively increases the attack surface and opens up to a variety of new threat vectors.
Please add this. I know it may not be easy, but I'm trusting on the only not morally corrupt browser organization to see that there is a real need for this.
