How to create custom view folder

Hello friends,
Please I want someone to help me on this.
I am trying to change the view folder to something else like "themes". And I will like this folder to be in the root directory.
I try using namespace to point the themes folder in the root directory i discovered you must create another folder name "Views" into the themes folders.

Here is what I need when I use the namespace to point to home.php

Codeigniter4 root directory => themes => home.php

instead of this

Codeigniter4 root directory => themes => Views => home.php.

I try this but not working

PHP Code:

function view(string $name, array $data = [], array $options = []): string
    {
        /**
         * @var CodeIgniter\View\View $renderer
         */
        $renderer = Services::renderer('themes'); // I try to change the directory viewPath but not working

        $saveData = true;
        if (array_key_exists('saveData', $options) && $options['saveData'] === true) {
            $saveData = (bool) $options['saveData'];
            unset($options['saveData']);
        }

        return $renderer->setData($data, 'raw')
            ->render($name, $options, $saveData);
 } 


I will always appreciate your help. Thanks
