Permission denied error when deploying neutron-sriov-agent

After enabling 'kolla_enable_neutron_sriov', service deployment fails with the following error:

fatal: [vs-os-comp-test-03]: FAILED! => {"msg": "Failed to get information on remote file (/etc/kolla/neutron-sriov-agent/sriov_agent.ini): Permission denied"}

The error appears to be a missing 'become: true' in the following task from the ansible/roles/neutron/tasks/config.yml playbook:

- name: Copying over sriov_agent.ini
  vars:
    service_name: "neutron-sriov-agent"
    neutron_sriov_agent: "{{ neutron_services[service_name] }}"
  merge_configs:
    sources:
      - "{{ role_path }}/templates/sriov_agent.ini.j2"
      - "{{ node_custom_config }}/neutron/sriov_agent.ini"
      - "{{ node_custom_config }}/neutron/{{ inventory_hostname }}/sriov_agent.ini"
    dest: "{{ node_config_directory }}/{{ service_name }}/sriov_agent.ini"
    mode: "0660"
  when:
    - neutron_sriov_agent.enabled | bool
    - neutron_sriov_agent.host_in_groups | bool
  notify:
    - "Restart {{ service_name }} container"
