Does resetting NVRAM reset EFI Boot Order? I've had a Macbook Pro for a year or so now and have experimented with quite a few Linux distributions which have added and changed things in the EFI Boot Order. I am looking to clean things up. The tool efibootmgr for Linux does let me make changes and cleanup as necessary. However will resetting NVRAM reset the EFI Boot Order for me?
NVRAM is a standalone chip on your logic board, backed up by small battery.

EFI resides on your SSD. (hard drive)

So no, resetting NVRAM will not impact EFI.

To restore EFI, you have to reinstall the OS X.
