Disable user authentication for a controller

Hi,

I want to disable user authentication for a controller. But I still need to authentication (bearer token should be valid) for this controller. And of course need authentication and user roles for other controllers. How can I disable role base auth for an controller/action?

My startup class contains:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseAuthentication();
    app.UseAuthorization();
    app.UseRoleAbility();
    ...
}

And my controller contains 

[Authorize]

attribute.
