Can I add an alias to an automation in automations.yaml?

I have an automation in automations.yaml that I can’t see in the UI. Can I safely add an alias line to this file?

- id: '1695917599255'
  description: ''
  trigger:
  - type: not_occupied
    platform: device
    device_id: 9f21dd08c5831174be3b24250bdf98b6
    entity_id: f3c056587e3369eeb15a6cac7ac2d4f5
    domain: binary_sensor
    for:
      hours: 0
      minutes: 1
      seconds: 0
  condition: []
  action:
  - service: switch.turn_off
    data: {}
    target:
      entity_id:
      - switch.vulcan_relay
  mode: single

Yes you can.
