Custom Query for blog or archives

Dear Support-Team,

I am wondering if I could filter the query for tag archives. I am using this code for the masonry element:

function avia_masonry_custom_query( $query ) {
	unset($query['post_type']['ABC']); // Custom Post Type "ABC"
	$exclude_cat = array('category__not_in' => array( 1, 2 )); // Categories by ID
	$query = array_merge((array)$exclude_cat, (array)$query);		
	return $query;
}
add_filter('avia_masonry_entries_query', 'avia_masonry_custom_query');

Is there a filter for the blog post element or even tag archives too? I have a certain tag archive with posts from different post types and I would like to strip all posts from one of the post types from the archive.

Any ideas?

All the best, Daniel
