Need help identifying and locating an annoying rubbing/flexing sound from my interior during acceleration and deceleration (not bumps) on my 2024 MYP.

Hey guys so I got this MY a few weeks ago and have been loving it outside of a few annoying noises from the interior. This interior flexing rubbing is really annoying, I recently tested two other model Ys from CarMax and neither one of them make this noise that mine does. It sounds like it's the whole interior just shifting as I get the car moving no matter how gently I accelerate or brake. It's noticeable at low speed only. My intuition is the door panels flexing or rubbing on something but it could also be noise from the seats rubbing? But I don't know and I'm in the process of getting Tesla service to look at it a second time. The first time they said it was normal. This time around they're going to look more into it but the tech was saying he thought it was like the door seals but he cleaned them once and it didn't make a difference and I just cleaned them again and still same noise. I really appreciate some help, it bothers me enough that it makes me want to see about getting a different car. Anyone know anything about this? Thanks!
