It is possible to open another instance of Abeyance with reset POIs and containers

So it turns out you CAN sort-of reset all the POIs on your Abeyance:

- Find the Portal on the Abeyance map

- Play your Abeyance Card (it is not consumed)

- Check the "Reset" box

- Ignore the scary message that suggests you will lose all progress in your Abeyance.

- Open the portal.

You can now go to a new instance of Abeyance with refreshed POIs and containers. NPC dialogs are not reset. Specific items (e.g., the Immolation scroll marked on the map) have tehir icons but the item is not there if you previously picked it up.

Despite the scary warning, if you click Return to Respite or Return to Crossroads, you will go back to the very first instance of Abeyance you entered. Apparently the portal to that Realm is "somewhere else" so you cannot go to that portal and Reset it away.

Really not sure if any of this is intended.
