AllowAnonymous attribute by CSharpControllerGenerator

[twtuck]

With CSharpControllerGenerator, can we generate a controller or action method annotated with the AllowAnonymous attribute?

Background: I enabled the authentication and authorization middleware in asp.net core, with the intention of having all endpoints protected by default. But there are a few endpoints that I want them to remain unprotected. For controllers I implemented, I can achieve this by applying the AllowAnonymous attribute. But for endpoints generated from openapi.json, I can't find seem to find a way for the same attribute to be applied to the generated endpoint.
