How to disable comments on specific post type?

I have a funeral home website. The obituaries are a custom post type. When staff creates a new obituary they select the service locations from a Post Object repeater field from Advanced Custom Fields PRO. So the Service Locations are also a custom post type. The issue is that the Service Locations are getting hammered with spam comments. If you can actually get to the Service Location pages there is no comment form. I actually created a template with no comments hoping to fix this. Now just the title shows on those pages.

I am using CPT UI and do not have the supports comments box checked.

I have also tried a plugin where you can select post types to disallow comments but they are still coming. Does anyone know how I can handle this?

Obviously, I can’t turn comments off completely because the condolences are through the comments.
