I want to delete the main avoig page

Kindly add the following code to the bottom of your theme’s functions.php file and replace the word “REDIRECT_URL” with the page URL to which you need to redirect the users when clicking the main AIOVG page.

function aiovg_videos_custom_archive() {
    if ( is_post_type_archive( 'aiovg_videos' ) ) {
        wp_redirect( 'REDIRECT_URL', 301 );
        exit();
    }
}
add_action( 'template_redirect', 'aiovg_videos_custom_archive' );

Hope this solved our issue!
