2017 macbook w/o touchbar got stuck in target disk mode after I tried to turn the target disk mode on in settings.

I tried to start in safe mode with Command+R and holding power buttons but not working.

Any suggestions please?

On your built-in keyboard, press and hold all of the following keys.

• • Control  on the left side of your keyboard
  • Option (Alt)  on the left side of your keyboard
  • Shift  on the right side of your keyboard

Keep holding all three keys for 7 seconds, then press and hold the power button as well. If your Mac is on, it will turn off as you hold the keys.

That is a firmware lock screen which requires the firmware password to continue. A firmware lock prevents doing anything except booting to the main internal boot drive, unless the firmware password is provided.

Set a firmware password on your Mac - Apple Support
