You can use the "vcex_grid_query" filter to tweak the query arguments for any Total WPBakery builder module that displays posts. The example below shows you how you can filter out the query for a custom Events Calendar Display. Note, the "vcex_grid_query" filter applies to ALL grids to target a specific module you can add a custom ID or classname to the module and then check for it in the $attrs variable which returns an array of all the shortcode attributes/parameters.
add_filter( 'vcex_grid_query', function( $args, $attrs ) {
// Alter arguments for Tribe events
// @see documentation here: https://theeventscalendar.com/knowledgebase/using-tribe_get_events/
$args['eventDisplay'] = 'custom';
// Return query arguments
return $args;
}, 40, 2 );
