Mine has it too. 2016 I bought used with 7,700. I now have a little over 9,000 and they squeak just a little, mostly just before a full stop.
“Gibraltar” 2016 white deluxe has been sold.
I'm hardly ever on here but, try putting a silicone based brake paste on the back of the pads. I work at Volvo and part # 1161688 works great I've had several new Harleys that had a high pitched noise and I put the paste on the back of the pads and never heard a noise again.
Good luck
