Not specifically but it can could be used for it. GraphQL just a message spec (like dare I say, SOAP). But if you use it with BFF then the value of the dynamic query aspects seems less valuable. With a BFF your App/UI and endpoints can be tightly coupled. If a specific page/component/action needs data structured in a specific way then you just make the endpoint do exactly that. You can accomplish this over GraphQL but it seems like an unnecessary extra layer at that point.
