If the mod 'Command Block Ascension' is installed in a modpack, the witherstormmod should Auto-Disable the House, cuz you can craft the Command Block anyways.

That would be the responsibility of the CBA developer. You can install the mod that disables the house spawn in the meantime.

I always installed all the mods on the server first and the Wither Storm Mod after loading X-0 Z-0. But how is the mod called so I can install it on later projects?

No Rundown House

As CubeGamer647 said, this would be something Command Block Ascension would have to do. You can also the no rundown house datapack Cube linked above to disable it as well.
