I never had any problems with my 2017 Axis. How tight does the fiberglass hood fit? Can it be adjusted (Might have to use washer at mounting points).
Does one side stick out further than the other?
I would use the weather stripping idea first.
I inserted stainless steel mesh screens in each of my slates of my grill (mostly to protect the radiator but also for looks).
No problem with noise before or after in installed the screens.
Its just 4 of the stainless steel gutter screens that keep leave out. Cost like $2 each (So $8.00 and some zip ties). Just tin sip to size, bend to shape and zip tie on each slate. Cant see the zip ties with the chrome grill cover on. It will stop a bird and large bugs and stones from entering the grill.
This might change the pitch of the noise or help eliminate it for less than $10.
