Has anyone tried cutting out the artificial sound

Seems like there is some confusion of the function of Active Sound Control, which creates the "artificial sound."
So there must be a way to unplug the control unit for ASC (maybe a fuse somewhere), which will get rid of the "steady tone of low and deep sounds" created by the actuator. By unplugging the vacuum, you are actually making the car sound louder, deeper, throatier in the interior when driving below 3600 RPM.
This edmunds long term vehicle update gives an explanation about the unplugging the hose from the vacuum.

An electronic control unit mounted beneath the instrument panel takes input from engine sounds, including varying engine speed, vehicle speed and throttle position and generates augmented sound through an actuator. It is entirely separate from audio system, so there’s no reduction in music fidelity.
Most importantly is the driver controls ASC. It’s activated only in SPORT S+ mode, not Eco, Normal and SPORT S modes. And when it’s on, ASC blends with the natural intake and exhaust sounds to about a 50:50 ratio.
At engine speeds up to 3,000 rpm, ASC issues a steady tone of low and deep sounds.
As revs rise, the tone transforms into a higher-pitched note that blends with the engine’s mechanical sounds, culminating in a free-soaring sound beyond 6,000 rpm.
