From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

WARNING: doing this will absolutely DESTROY YOUR SYSTEM, PERMANENTLY!!!

But if you wish to continue, you can erase all the EFI variables using the rm utility, I dont think you will be able to completely zero out the chip on the system from inside of Linux as its read-only.

But to delete all the EFI variables, cd into /sys/firmware/efi/efivars, if this directory is not availiable, either the efivarfs is not mounted, or you are booted in legacy BIOS mode. But once you are in this directory, run chattr -i ./* as root or sudo to remove the immutable bit on all the files, then run rm ./* as root. This WILL break your system. Only do this if you know how to restore your system using like a chip programmer.
