You can easily add your own custom attributes to <body> tag. There has a filter bricks/body/attributes. Open the functions.php file of the bricks child theme or any 3rd party snippets plugin and drop the following PHP code
add_filter('bricks/header/attributes','my_body_id');
function my_body_id( $attributes ) {
$attributes['id'] = "enter-your-id";
$attributes['data-my-att'] = "enter-your-attribute-value";
return $attributes;
}
