I used this manifest after enabling datadogmonitors in datadog operator manager.yaml file:

apiVersion: datadoghq.com/v1alpha1
kind: DatadogMonitor
metadata:
  name: datadog-monitor-test
spec:
  query: "avg(last_10m):avg:system.disk.in_use{*} by {host} > 0.5"
  type: "metric alert"
  name: "Test monitor made from DatadogMonitor"
  message: "We are running out of disk space!"
  tags:
    - "test:datadog"
  options:
    renotifyInterval: 1
    renotifyOccurrences: 3
    renotifyStatuses:
      - "alert"
      - "warn"
    groupbySimpleMonitor: false

The renotifyStatuses were subsequently shown on the monitor's settings:
