Break Link From Original File

Hello,
I download STEP files from websites that provide 3D CAD models. After opening these STEPs, I need to perform break link from original file for each one. I can automatically change the units, but I can’t automatically break the link. Can you write and provide the code for this?

Turn 3D interconnect off.

This will import parts without the link. (however, the import may be less robust with 3Dinterconnect off).

You are magnificent. Thank you very much.
