Direct models of Inventor, I don't believe so (but I could be wrong). You could export to other supported file types that 3DS Max could import.
Update: Clarification....
I believe 3DS Max has to be the same version as the Inventor model or newer.

Hi! I believe you can export it to sat, step, or stl/obj from Inventor 2019. 3D Max 2018 should be able to import the files.
Many thanks!
