Acquire a villager, place down a workstation for it to claim.
Once villager has claimed workstation, complete a trade.
Turn the villager into a zombie villager then proceed to cure.
The cured villager will forget the workstation it last worked and and will not reclaim it once cured. Replacing the workstation does not seem to make the villager reclaim it either.
They won’t restock due to this issue.
