Deleting Sites for Downtime. It's possible?

Hello guys

Well, I assume this topic may NOT be recurring around here. I've searched - a lot - without success for a job that's on my desk and humbly asking for help.

So in an organized way, straight to the point:

- Using Sharepoint, either as a site or as a fileserver, it was determined that files - without retention policies - are deleted after a certain period. Six months for example.

Well, a site, created from a Teams Team, I asking for its expiration, it deletes itself and takes everything together, Team, Channels, Document Library, Sub-sites and so on.

The question is: Can I set an "expiration" time, something similar to Teams for Sharepoint sites, precisely so that this removal and deletion takes place in a certain time?

If so, could you point me to the documentation, FAQ, Help so that I can test it?

Thanks a lot for the help
