I was able to delete the fleet_server_host using the api - i also had to set default to false first.

GET kbn:/api/fleet/fleet_server_host

PUT kbn:/api/fleet/fleet_server_hosts/b1bfad95-0361-49bf-8d3d-060b2f41eb57
{
  "is_default": false
}

DELETE kbn:/api/fleet/fleet_server_hosts/b1bfad95-0361-49bf-8d3d-060b2f41eb57

{
  "items": [
    {
      "id": "b1bfad95-0361-49bf-8d3d-060b2f41eb57",
      "host_urls": [
        "https://fleet-server-prod-fleet-server-agent-http.elastic-system.svc:8220"
      ],
      "is_default": true,
      "name": "fleet",
      "is_preconfigured": false
    }
  ],
  "page": 1,
  "perPage": 10000,
