Transparent menu by default + Hide Portfolio options below Avia Builder

Hi,
I am planning to use a transparent menu throughout my page as I am using a slider in the page builder. Is there way to set it as a default option for all pages and even custom post types that include the option?

Also, I’ve added the page builder to a custom post type following some of the codes shared in the forum but I noticed that the portfolio settings metabox shows when using this code:
`add_filter(‘avf_builder_boxes’, ‘avia_register_cpt_meta_boxes’, 10, 1);

function avia_register_cpt_meta_boxes($boxes) {
if( !empty($boxes) ) {
foreach($boxes as $key => $box)
{
// Use Name of CPT you want to use. The name taken from register_post_type function for example
//
// Can duplicate just the following line to add more CPT
$boxes[$key][‘page’][] = ‘webinar’;
$boxes[$key][‘page’][] = ‘event_room’;
}
}
return $boxes;
}`
