Even if you could do that - which AFAIK, you can't - Woodcutter camps have an internal storage limit: you would eventually fill up with the don't-deliver-materials, and then workers wouldn't be able to do anything, including cutting trees down (because they need space for what they chop). With the exception of the warehouse(s), the same is true of basically every building in the game.

If this irks you that much, you might more need a mod that disables disables secondary resources gathered from trees. And/or perhaps disables storage limits/changes the storage mechanics.

I think the only way to make them NOT deliver wood (and Resin and other goods) is to build a new Camp and destroy one with goods in them. But why? You need goods.

Trees have secondary resources at a % chance. So they're delivering the resources they gained to the storage warehouses. These are usually CRUCIALLY needed resources so.its a bit of an overrreaction to be upset about it.. And as stated there is a limit to how much camps hold. This isn't a typical strategy like Age of Empires types of things. Its just done differently. Adapt. Literal slogan of the game is to adapt to your surroundings. Adapt to a differently done game.

If you could forbid it at the warehouse then it would prevent it from anything.. so good job starving your settlement. :)
