Humming on 2022 g80 sport prestige

[Svenergy]

So I have noticed a humming or some sound it get loud between 65 and 79. At 80 it goes away. It gets worse when you let your foot off the gas and car slows down. I keep checking tires and they are not wearing crazy or anything and checked allignment not sure if it's the pirelli tires or the differential or transmission car has 4100 miles on it.
Anyone have any ideas. I seen people with gv80 having diff. Issues...
