How do I programmatically fix local menus to be shown only for a content type?
I don't konw if there's a better way to do it now but few years ago I did it using a custom access: https://stackoverflow.com/questions/36496998/drupal-8-how-to-add-task-and-contextual-links-for-specific-node-type/36636263#36636263
In my case it was easier because I was creating the routes in my module.
Since your routes are created by views you would need to implement a RouteSubscriber to alter the route, add the _custom_access and _node_types requirements.
/!\ Warning: I am not sure since I never tried it on views routes but it might conflicts or breaks the rules you've set from the views UI to access this view. It should be compatible with a _permission rule, maybe not with an _entity_access rule.
