• You won't need any such management if the user is logged in, because it becomes part of the tenant as soon as it logs in the user.
• For anonymous users, there are usually very few use case scenarios because the features available for anonymous users are usually very limited. If you want to make sure those requests still follow some tenant, you need to place a TenantSwitch from System module to be called on an appropriate client action (like OnReady) of the screen or web block in concern.

Note that you cannot configure or attribute a module to be dedicated for a specific tenant. You can logically do that from your code, but there's no such configuration.
