Disconnect Zoho Inventory and Zoho Books

Disconnect Zoho Inventory and Zoho Books

This may be an uncommon request, but is there a way to disconnect our Zoho Books and Zoho Inventory accounts, so that invoices in Zoho Inventory do not automatically get created in Zoho Books? I cannot find any way to disconnect them from the integration page of either system.

The short version is that we use these systems for two very different things, so we don't actually want them talking to each other.
