buying toyota's lift kit?

So, I asked my mechanic to look into Toyota's new lift kit for me because its not approved for my truck.(2021 trd sport) What he came up with after talking to a dealer here in Canada, is that there is no reason not to put it on my truck. Toyota, however, absolutely will not sell this lift without proof of an approved model. Question, is this the policy in the States as well, or will they sell me one? Or does anyone know of any way that I can get my hands on one?
Sorry in advance if this is like beating a dead horse for some.

 

I am not currently a happy person with Toyota. Yes, they require a vin number to order parts, but will not go above and beyond to provide advice or answers. Afaic they are as useless as the cashiers at McDonald's that just push the pictures.
Tye way to get what you need is to get the vin number from the model the parts are for.... don't use your vin#.

 

Just get a Vin# from the vehicle it goes to, thru carvanna or wherever, and use that.
Welcome aboard

 

Apparently they need photos aswell. Not sure if this is true or not though. What is carvanna, i've never heard of that
