Yesterday, 1 year and 1 day after Get N Dirty posted his video and just over 9,000 miles on my truck, I had the exact same issue pop up on my 2019 Laramie. I received a call while listening to Sirius XM and I used the "answer" touch point on the screen. The noise immediately appeared and I had to terminate the call because I could not hear the guy. I tried to call the guy back but the noise persisted. After three attempts, I had to turn blue tooth off and the radio off to make my call exclusively on the iPhone. After that, the noise persisted in all modes. I had my wife connect her phone to Bluetooth thinking it might "break the cycle" but that did not work either. I basically had to leave the radio off for the day. This morning, it's not making the noise. Seems enough folks are having the issue, there would be a better solution communicated by Ram than take it to your dealer to see if they can duplicate the issue. These are expensive trucks.
