Is there any way to create a block template for a single page or page template?

I have been trying to create a block template but only want it to show up on the “Home” page for the website. I have not found any way to make this work as I cannot access anything but the post ID in the “init” hook and this theme runs on multiple websites with different post IDs for the page called “Home”

I am looking for ways to somehow make this work so when a user goes to edit the “Home” page under Pages, they are shown the block template that cannot be removed or re-arranged.

function create_homepage_block_template()
{
    if (!is_admin() || !is_page('Home')) {
        return false;
    }

    $post_type_object = get_post_type_object('page');
    $post_type_object->template = array(
        array('homepage/featured-content', array(
            'align' => 'full',
        )),
        array('homepage/featured-modules', array(
            'align' => 'full',
        )),
        array('homepage/posts-box', array(
            'align' => 'full',
        )),
    );
    $post_type_object->template_lock = 'all';
}
add_action('init', 'create_homepage_block_template');
