I need some advice on this topic as well, please feel free to chime in.
I bought a new 2023 Lexus ES350 in September, 2023 from Oakland Lexus and got the same wind noise problem at freeway speeds, I test drove a few cars of the same model/year and detected the same issue. This service department won't fix it since I guess nobody wants to admit they sell low-quality cars. It looks like a build problem from a manufacturing plant since this happens often enough.
You can open a case w/ Lexus HQ in November 2023 and ask them to find a resolution (my case number is 231127003078.) Let me know how it goes.
PS: a dealership in Kentucky actually did fix the problem so we have a precedence here, I am disappointed with how Lexus handles customers nowadays.
