Is it easier for you perhaps to end the items for the whole period you are away, as I'm not sure if logging in from Pakistan might cause some queries / issues.
You are correct that Time Away offers a short term answer, that is, 30 days. For longer periods, simply end all items they will go into your unsold listing, or into the newly name ' Inactive listings! ' 🙄
If you are on My eBay selling they will remain there for 60 days, and if you're on the Seller Hub, they stay there for 90 days ready at any time during those periods for relisting.
