Hide block for specific content types?
You can use this module:

Block Visibility Groups

Here you can configure a visibility group which hides blocks for a specific content type.

The visibility groups not only provide more options for block visibility, they are also reusable, that means you can apply the same settings on multiple blocks.

Ctools also provides the functionality to hide blocks for content types, but there was an issue, I don't know if this is resolved.
