magento2 – How can I allow disabled or out of stock product to be ordered by admin order in Magento 2

How can I allow disabled or out of stock product to be ordered by admin order in Magento 2 without allowing backorder so that it is not allowed at the frontend.

I have found that in the particular case the quote item object set isDeleted true for the item, so it gets removed from the quote on the following section refresh.

Any guidance would be appreciated.
