For Explicit Subtraction,
- Ansys Mechanical does not do implicit subtraction
- Ansys Electromagnetics modeler command Modeler > Model Preparation > Perform Explicit Subtraction can do explicit subtractions before sending geometry to Ansys.
For example, consider the following model:

Perform Explicit Subtractions can be executed:
