Is there a way to call 3D Slicer libraries without running the 3D Slicer program?

Operating system: Windows 10
Slicer version: 4.11.20210226

I want to use 3D splicer libraries for a full-body mesh. Nothing more, and not complex. I want to call the 3Dsplicer libraries without opening the program. It could be through a command-line interface. Is there a specific call line?
