How can I modify or filter this variable in an existing class? (Mai Theme)

Sometimes it takes asking a question to find out the answer.

function my_attachment_grid() {
    $args = [
        'post_type' => 'attachment',
    ];
    add_filter( 'post_query_args', 'my_filter', 10, 1 );
    do_grid( 'post', $args );
}

function my_filter( $args ) {
    
    $defaults = ['post_status'=>'inherit'];
    $args = array_merge( $args, $defaults );

    return $args;
}
