How to adjust inventory threshold in an omni channel store?

[TBS2022]

Hello

I have an omni channel store

1 online - 1 brick & mortar - 2 warehouses.

My Brick & Mortar store will sometimes have items that only have 1 item in stock as it is a display item.

How can I stop selling from this location and use stock from the warehouse when inventory threshold reaches 1. I do not want to sell the display item.

Can I set my online store fulfillment center to be 1 warehouse and my brick & mortar (POS) from another warehouse?

thanks
