$kirby->root('blueprints')

If you want to overwrite the root you can do this in your index.php by passing a custom roots setup to the Kirby constructor.
<?php
include 'kirby/bootstrap.php';
$kirby = new Kirby([
'roots' => [
'blueprints' => '/absolute/path/to/custom/root',
],
]);
echo $kirby->render();
