Issue Control time of day Let's Encrypt performs renewals?

[HostaHost]

Currently Let's Encrypt seems to just fire off renewals whenever it feels like it if the number of days in advance is reached. Is there a way to set "off hours" or adjust a schedule on the Plesk side to not renew certificates during the middle of the day, given they require an outage from the web server restart?

There are two cronjobs which might be responsible for the renew task:

Since the scripts itself are encrypted this is just a guess but the original timings are corresponding with the renewal mails. May you give it a try.
