Information
Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions).
It is detrimental for software products to provide, or install by default, functionality exceeding requirements or mission objectives.
DBMSs must adhere to the principles of least functionality by providing only essential capabilities.

Solution
On data-bearing nodes and arbiter nodes, the mongodb-enterprise-tools, mongodb-enterprise-shell and mongodb-enterprise-mongos can be removed (or not installed).
On applications servers that typically run the mongos process when connecting to a shared cluster, the only package required is the mongodb-enterprise-mongos package.
