How do I rename EC and OSI? I've looked everywhere online.

I'm attempting to Hackintosh out of my ZenBook ux331fn.

I'm using OpenCore, and this guide: https://khronokernel.github.io/Opencore-Vanilla-Laptop-Guide/config.plist/coffee-lake-8th-gen.html tells me i have to rename EC and OSI. Thats it. Thats all it says. I am going insane here.

Where do I rename it and how?

Thanks
