Disable trackpad feedback? Don't want any tactile/haptic feedback when clicking

I have a 12" Macbook (2015) and a Macbook Pro (2017), both running MacOS 10.13.6. The 12" gives me the option for "Silent Clicking" in Trackpad Preferences. The MBP, however, does not give me this option (and I wish it did). So, while it does seem to be capable of being switched off, there does seem to be some hardware-specific aspect to it. Silent mode is nice... wish they all did it.

I think it's not possible to do using a "normal" way, it's restricted to the Service team only. Though it's possible ultimately, the motor probably needs software to tell it whenever to vibrate, it's just that the software is not accessible normally, I believe.

By the way, I current have the problerm, the Taptic motor stopped working but the 4 sensors still are working so I kind of using a "TRUE solid-state" trackpad, everything works except the Taptic, it's cool, I think it's the best "issue" you can ever get on your Mac, it feels great.
