Having the same controller code for multiple HTTP methods, is it possible to hide only one of them from Swagger UI?

Question

The same method and the same route are used for two different endpoints: one is a GET, the other one is a POST. Is there a way to hide only one of them (e.g. just the GET one) from the Swagger UI?

[Route("myroute")]
[HttpPost]
[HttpGet] // This is being keep for compatibility purposes (legacy services that are still using it)

I tried using the IgnoreApi property (see below) with no luck: it hides both the GET and the POST. Seems like it hides the entire route, no matter the HTTP method.

[ApiExplorerSettings(IgnoreApi = false)]

Not on the same endpoint. The ApiExplorerSettings Attribute is for the entire method and cannot be applied to a specific Attribute accompanying the method.

What you can do is the following:

[HttpPost]
public void MyCurrentMethod() {
    //Do stuff...
}

[ApiExplorerSettings(IgnoreApi = true)]
[HttpGet]
public void MyDepricatedMethod() => MyCurrentMethod();
