configure Auth component differently per scheme

Question

I'd like to add an API to an existing app using the Auth component and Form scheme authentication, using Basic authentication.

This is the configuration I think I would like to have, but I'm not sure if settings can be entered in a per-scheme way.

Alternatively, is there a way to change Auth component settings based on the route? For example use Form based unless the url extension is json, in which case use Basic?

$this->loadComponent('Auth', [
    'authenticate' => [
        'Form' => [
            'fields' => [
                'username' => 'email',
                'password' => 'password'
            ],
            'loginAction' => [
                'controller' => 'Users',
                'action' => 'login'
            ],
            'storage' => 'Session',
            'unauthorizedRedirect' => $this->referer()

        ],
        'Basic' => [
            'fields' => [
                'username' => 'username',
                'password' => 'api_key'
            ],
            'storage' => 'Memory',
            'unauthorizedRedirect' => false
        ]
    ],
    'loginAction' => [
        'controller' => 'Users',
        'action' => 'login'
    ],
]);
