In our Jamf Protect tenant, we have a multitiude of devices that have been retired and no longer in use.  They still show in Jamf Protect unless we manually delete them and skew our results.

Is the correct process to keep our Jamf Protect Computers inventory tidy to manually delete them from Jamf Protect?  Does Jamf Protect have any auto-expire policies?  For example, if disconnected for 6 months then purge device from Jamf Protect.
