High Pitched Ringing at exactly 70 MPH

Hey Tacoma world, need some help diagnosing a strange noise that’s started in the last couple months.

At exactly 70 MPH, I can hear a very high pitched ringing or whistling noise. I can’t really tell, but it seems like it might be getting slightly worse over time. It’s super abrupt at 70 MPH, and I can occasionally hear it a little quieter at 41 MPH, but not as reliably as I can hear it at 70 MPH. It doesnt really change under different engine loads or throttle positions.

Some additional info, my truck is a 2019 TRD Pro (automatic) with 93K miles, 5.29 regear (installed around 55k miles), Magnuson super charger (installed at 80K), bedcover, rock sliders, and 265/75r16 wild peaks. Apart from that the truck is stock.

See linked video to hear the noise while driving: https://youtube.com/shorts/bTSmey-fyaE?si=j78IROSXCOYS6hbe

Any ideas what this might be? It definitely sounds different from the diff howl I’ve had for the last 4 years or so after my 5.29 regear. My initial thoughts were drivetrain or something to do with a supercharger bearing or some kind of leak? Curious if anyone else has had this happen? Thanks in advance for the help.
