How to removing certain core Gutenberg blocks on some Page Templates / Post Type

Question

As per WordPress,

apply_filters_deprecated( 'allowed_block_types', bool|string[] $allowed_block_types, WP_Post $post )

Warning: This hook has been deprecated. Use the ‘allowed_block_types_all’ filter instead.

Below code is not working now.

add_filter('allowed_block_types', function($block_types, $post) {
  $allowed_blocks = [
    'core/shortcode',
    'core/image',
    'core/gallery',
    'core/heading',
    'core/quote',
  ];
  if ($post->post_type == 'page') {
    return $block_types;
  }
  else
  {
    $blocks_to_remove = [
      'acf/editor-intro',
    ];
    return array_diff($allowed_blocks, $blocks_to_remove);
  }
}, 10, 2);

You can use the below hook I have created some conditions like Post Types / Page Templates / etc.

add_filter('allowed_block_types_all', function ( $block_editor_context, $editor_context ) {
    if ($editor_context->post_type == 'page') {
        // Here you can check any Post Types
        return array(
            'core/paragraph',
            'core/heading',
            'core/list',
            'core/quote', // Above are few example
            'acf/test-block' // you can allow disable custom ACF blocks also
            );
    } else if (basename(get_page_template()) == 'template-custom.php') {
        // Here you can check any Custom Templates
        return array(
                'acf/test-block' // you can allow disable custom ACF blocks also
        );
    } else {
        // Here will return all default blocks
        return $block_editor_context;
    }
}, 10, 2 );

Below are some default blocks so you can remove as per required with hook.
