Restricting page templates by blog_id in multisite network

TL:DR; Is it possible to restrict page templates to a certain site within a multisite network? (Using something like get_current_blog_id for e.g)

More details

I’m building out several websites that each use the same base partials, just in different variations in their page templates. For e.g Site A Site B’s home page both use Components A - D, however Site A’s goes A B C D and Site B’s goes C B A D. All my actual markup goes into the component partials and the page templates are mostly just a list of includes (using Roots Sage theme to help pass data).

This is the basic premise but we’re talking +-30 components and +-50 templates across 7 websites.

I’ve got all my templates in a subdirectory in my theme folder (e.g template-home-site-a, template-home-site-b) however this means when a user is working in the CMS for Site A they get a list of 50 templates, rather than just ones specific to Site A which might only be around 12.

Is there a way to possibly hook into Wordpress’ templating system and add/remove folders it looks in based on the current blog ID? Open to any other suggestions.

I know it is a bit old question. But I hope some one can find it usefull. If for some reason you can't use child-theme (like me) there is hook theme_page_templates Accordint to developer WP Page Templates. Example:

function makewp_exclude_page_templates( $post_templates ) {
  if ( is_multisite() && !is_main_site() ) {
    unset( $post_templates['wp-templates/iframe_container.php'] );
    //In my case this one is removed from the list on every page other than main site
  } 
  return $post_templates;
}
add_filter( 'theme_page_templates', 'makewp_exclude_page_templates' );
