How do I disable some inspections for modules in IntelliJ IDEA?

Question

In IntelliJ IDEA, I can disable some inspections for a class, method, or other units. I have a module in a project that's a library that I am not the only consumer of. I do not use all the methods in the library and consequently a large number are marked 'unused'. These are all false positives. I would like to disable these inspections for this module alone (ideally, I'd like to disable unused warnings for public/protected methods).

Is this possible? If so, how would one go about doing this?

You need to define a custom scope and configure the inspections' scope.

1. Go to Settings -> Appearance & Behavior -> Scope and create a new scope. Include recursively all files, then exclude the given project library.

2. Then go to Settings -> Editor -> Inspections and choose the inspections you want to disable for that project library, e.g. Declaration redundancy -> Unused declaration. In the severity settings (on the right side under "Description") choose your newly defined scope.

Per default the severity settings look like this (if the settings apply for all scopes):

How it looks if the inspection is disabled for a scope named "Library Modules":
