Is there a different fastboot command for the Google Pixel and the oem-off-mode command? I'm trying to set a Google Pixel to boot when the power is connected. I found discussion of using the fastboot oem-off-mode charge = 0 command, but when I reboot the device into the bootloader and try the command I get a fastboot: usage: unknown command oem-off-mode error. 

Is this command no longer supported or did they rename the command?
I had a hyphen in the wrong spot. The proper command is fastboot oem off-mode-charge = 0
