you can make it so the base raising tools are showing up less frequently. That's about the only way on console at the moment
On the contrary, you can remove all the raidtools so they dont appear at all or even exist in the game. You dont need any of those tools for building, spawn in planks and logs ready for taking, increase the hammers and shovels, youre done. You got yourself a server with no tools to raid, only to build.
