There is a integration called Certifcate Expiry you can install:

Then run an automation that will update the cert when it is within 30 days for expiration:

alias: Renew Let's Encrypt if Cert Expiry less than 30 Days
description: ""
triggers:
  - trigger: time
    at: "01:00:00"
conditions:
  - condition: template
    value_template: >-
      {{
      (as_timestamp(states('sensor.YOURINTEGRATIONHERE_expiry'))
      - now().timestamp()) / 86400 < 30}}
actions:
  - action: hassio.addon_start
    data:
      addon: core_letsencrypt
mode: single

There could be a problem on system reboot that this runs before your webserver is up, so restart the Certificate Expiry after two minutes from reboot:

alias: Reload Certificate Expiry After NGINX Start
description: ""
triggers:
  - trigger: homeassistant
    event: start
conditions: []
actions:
  - delay:
      hours: 0
      minutes: 2
      seconds: 0
      milliseconds: 0
  - action: homeassistant.reload_config_entry
    metadata: {}
    data:
      entry_id: 01J__YOURENTRYIDHERE_FD
mode: single
