No.
Your AoH platform works as one cohesive unit. When a client is added to your AoH platform as a member they are given access to all of the tools in your platform.
Clients could choose to remove themselves from individual tools via unsubscribing from the tool or failing to accept the activation invitation (system of enrollment is unique for each tool). In this case, the client would remain an active member of your AoH platform but not use/access the various tools you had provided them.
