Does default authentication scheme must be excuted when AuthenticationSchemes is set to others?

[luoxlgh]

We have two authentication shemes named "custom1" and "custom2". The code is:

var authBuilder = services.AddAuthentication("custom1");
authBuilder.AddJwtBearer("custom1", options =>
{
    options.EventsType = typeof(Custom1AuthJwtBearerEvents);
});
authBuilder.AddJwtBearer("custom2", );

The controller code is:

[Authorize(AuthenticationSchemes = "custom2")]

The above authentication scheme would run into Custom1AuthJwtBearerEvents, and the authentication result is failed. But the result doesn't affect custom2's authentication result.

There is a related solution: https://stackoverflow.com/questions/60957438/how-to-disable-the-default-authentication-scheme-when-non-default-schema-is-pro

But it is confusing that the default scheme is still excuted even when the authentication scheme is set to others, is it the expected flow?

Is there any solution to aovid excute default scheme without modify the usage?
