How to restrict block for particular subpath, yet allow for all other subpath of a specific parent path? I have created the custom page and assigned for the Underwriting content type nodes like underwriting/, but I want to restrict the block for a node of that content type; for example, show it for underwriting/, but not for  underwriting/example.

Is it possible to restrict a block for particular sub-path, and allow it for all the other sub-paths of a specific path?
Assuming all of your underwriting/* nodes are of a certain content type and this content type does not have anything else than underwriting/* as path

Go to /admin/structure/block and find your block and click on Configure link.

Then under Visibility settings, Pages tab, select all pages except for underwriting/example



and then
