STEPS TO REPRODUCE

I'm trying to run the following task:

- name: Setup NTP
  arista.eos.eos_ntp_global:
    config:
      authenticate:
        enable: false
        servers: false
      local_interface: "Management1"
      servers:
        - server: "0.pool.ntp.org"
        - server: "1.pool.ntp.org"

EXPECTED RESULTS

I expect the switch config to be:

ntp local-interface Management1
ntp server 0.pool.ntp.org
ntp server 1.pool.ntp.org

ACTUAL RESULTS

However the command 'ntp authenticate' is still on the switch causing ntp sync to fail

ntp authenticate
ntp local-interface Management1
ntp server 0.pool.ntp.org
ntp server 1.pool.ntp.org
