Just FYI, UEFI variables are stored in the flash by UEFI firmware. 
Almost nothing is stored in the CMOS NVRAM on modern PCs.

That is a pure guess based on no evidence, AFAICT. It is quite easy to 
find the UEFI variables in the flash image, once it has been read out, 
as the variable names are there in ASCII for those variables that have 
been set to non-default values.
