If it's in-chip, it won't be with PCB traces, it would be solid state inside the chip and you wouldn't be able to verify without inspecting the wafer, which is way outside my area of expertise. It doesn't sound like there's a mechanical relay that they are using for this.
There's also that if it's inside the chip, there is a risk that malicious software or buggy firmware can still enable it against your permission.
With a Framework laptop you can peel back the bezel and it's right there in plain sight. If the switch is in the off position it's a hard physical break to the microphone circuit. There is no possible software that can enable the microphone.
