Need Help Removing Sidebars from Custom Post Type Archives

I’m building a site with a custom child theme and having trouble
removing sidebars from our custom post type archive pages.

Setup:
– GeneratePress Pro (latest version)
– Custom child theme
– Custom post types registered via plugins
– Custom archive template at:
https://zippicks.com/vibes/

Issue:
The sidebar still appears on our custom archive pages (e.g., /vibes/) despite trying
multiple approaches:

What I’ve tried:
1. Adding filters in the template file:
remove_action(‘generate_before_main_content’, ‘generate_construct_sidebars’);
add_filter(‘generate_sidebar_layout’, function() { return ‘no-sidebar’; });

2. Adding hooks in child theme functions.php at various priorities
3. Using CSS to hide sidebar elements with !important
4. Removing all sidebar-related actions

None of these approaches have worked. The sidebar continues to display.

Questions:
1. What’s the correct way to remove sidebars from custom post type archives in
GeneratePress?
2. Are there GP Premium modules that might be overriding these settings?
3. Is there a specific hook timing/priority I should use?

Any guidance would be greatly appreciated. Thank you!
