How to call a Controller method which is accepting two models?

I would say that instead of justifying this lack of support of multiple models with documentation, you should find an argument in terms of software architecture perspective: ASP.NET Web API is built on top of MVC paradigm, where a view is bound to a model and handled by a controller.
In other words: 1 Model, 1 View, 1 Controller.
Your use case shouldn't be solved with 2 models, but using a DTO. Instead of binding 2 parameter to 2 models, design a DTO which includes both models as associations of the whole DTO:

// You don't need [FromBody] since complex types are already taken
// from the request body
public IHttpActionResult DoStuff(SomeDto dto)
