Installing a package with Ansible and not starting the service

Question

I have the following play snippet:

 27   - name: ensure necessary packages are installed
 28     apt:
 29       state: present
 30       name:
 31         - apache2
 32         - libapache2-mod-rpaf
 33         - nginx

I don't run IPv6 (LAN) so I have ipv6.disable=1 in my boot args. When Ansible installs Nginx, it defaults to listening on listen [::]:80 default_server; and returns an error in the play. How can I tell Ansible/apt not to start Nginx (or any service for that matter.. probably the same story with Apache) when installing the package?
