Disable Automatic Model State Validation in ASP.NET Core 2.1

ASP.NET Core 2.1 introduced the APIController attribute which performs automatic model state validation and in case of an invalid model state, responds with a 400 bad request error. When the controller is decorated with APIController attribute, the framework would automatically register a ModelStateInvalidFilter which runs on the OnActionExecuting event. This checks for the model state validity and returns the response accordingly. This is a great feature, but sometimes you want to return the custom error instead of the 400 bad request error.
