[Controller/Infra node removal] [openstack-ansible] Need to remove infra/controller node from environment.

Hello Team, Is it possible to remove an infra host from environment? If yes, can you please share the exact steps that need to be followed. I am trying to remove it manually by destroying all lxc containers from infra host which needs to be removed and then running setup openstack playbook. but it is not working properly. Can someone please share the exact steps needed to be followed to remove infra host from the environment. Openstack version: Wallaby or Yoga. Regards, Danish
