I had the same problem on my 2019. Inner tread on Both rear tires worn enough to cause noise from tires. I finally got an alignment at 30k. They made a toe adjustment to Rear Tires of both sides. I was worried that getting an alignment now with irregularly worn tires would cause my alignment to be off when I finally get new tires. The tread depth on the rear tires are like new. The tech informed me that the alignment angles are taken from the metal wheel and not from the tires, so I shouldn't worry, my alignment will be fine when I get new tires. I will live with the tire noise which should go away when the cupped tread catches up with the rest of the tire.
