I have a custom post type called book where I set 'has_archive' => false. When I access mywebsite/book, it's loading mywebsite/book/book-1, but I'm expecting load the 404 page. Is this a WordPress feature? How can I disable/change this?

Is this a WordPress feature?

Yes, and the redirect is being done by redirect_canonical(), but the URL is determined by redirect_guess_404_permalink():

redirect_guess_404_permalink()

Attempts to guess the correct URL for a 404 request based on query vars.

So what's happening in your case is, WordPress attempts to find a post having book in the slug (post_name), and then if found, WordPress loads that post instead of showing a 404 error page.

How can I disable/change this?

1. Completely disable redirect_canonical() (which WordPress core hooks on template_redirect) if the current URL path is exactly book as in example/book/ and example/book?foo=bar.

   So for example, you can use the parse_request hook to disable the canonical redirect:

   add_action( 'parse_request', 'wpse_392546' );
   function wpse_392546( $wp ) {
       if ( 'book' === $wp->request ) {
           remove_action( 'template_redirect', 'redirect_canonical' );
       }
   }
   

2. Or you can use do_redirect_guess_404_permalink to disable just the attempt of guessing the correct URL as mentioned above.

   So you could use the same hook and function as used in option 1 above, but replace the remove_action() line with:

   add_filter( 'do_redirect_guess_404_permalink', '__return_false' );
