It is your school’s Chromebook? Yes, there are ways, but if you don’t want to fuck up your school computer, then I suggest you don’t do it. They disabled developer mode for a reason, and once you walk the path, you can never turn back. There is way, but I am merely stating it.
 
1./Make sure your Chromebook is off.
2./Unscrew your Chromebook back cover.
3./Unscrew the battery and unplug the power cord connecting the battery and the motherboard.
4./Open your Chromebook and press the power button for 30 seconds. This should bypass the admin block.
5./Place the battery back in and connect the power cords. Put the back cover on.
6./Turn your Chromebook on and press esc + refresh + power It may take 9-15 minutes to boot based on your device. Do not follow this step until you reach the chrome screen.
7./When you reach the "Chrome Os is missing or damaged" screen press Ctrl + d.
 
The school will definitely notice you did this, especially if they have monitoring software. So, good luck.
