Can I prevent customers from ordering certain stock on my website?

Hey guys,

We currently drop ship all of our products. We're getting our own stock which our supplier doesn't stock and it's going to be advertised as an (offers page). Obviously, this may cause some issues in the long run with shipping. We want to make it so that if customers order from our stock they can't buy the stock from the drop shipping supplier, is this something that can be done without creating a new website?

Many thanks,
