How do you use SmokelessRuntimeEFiPatcher?

Hi,

Saw this new tool being mentioned in other threads and it sparked my curiosity. Was wondering how do you use it? For example how would you add an Efi module into your bios? How does it work? Confused about does it permanently insert modules and make patches upon request into the bios? What about if the bios is protected with Boot guard, secure boot, Dell, Lenovo or otherwise…

Thank you
