Reset NVRAM, PRAM, and SMC, all in one go from the terminal?
I'd try with a script using the following outline

sudo nvram -c


which should clear the contents of NVRAM.

curl 'https://sourceforge.net/projects/refind/files/0.11.4/refind-flashdrive-0.11.4.zip/download' --output refind.usbimage





copy SmcFlasher there (https://discussions.apple.com/thread/4855319?answerId=22024754022#22024754022)

shutdown -r now


and then you will have to manually follow the smcflasher instuctions up to

SmcFlasher.efi -reset 1


you can of course automate that as well by modifying the USB image accordingly and you'd be right where you want to be.
