Rename generated class FileResponse

[Kipotlov]

Hello,
I added a new endpoint in my controller that return an FileContentResult.
When I'm using NSwag studtio to generated the c# client, it generates the class FileResponse as return value for my new endpoint.

The problem is that I already have a class named FileResponse in my generated class.
I cannot rename it because it will cause a breaking change.

I also would prefer not to return a custom class and keep the asp.net way to do it (use ControllerBase.File() method).

So my question is : Is there a way to rename the class generated by NSwag Studio?
I looked at the options in the software and I didn't see anything.

Thanks for you help
