Chromebook connect to ad

Just wondering if anyone has come across a way to join a Chromebook to ad without having to use google services I have a Lenovo Chromebook (I think model number is 340-14) from what ive read it’s a Gemini lake (laser14) I would have just removed chrome OS and put Linux on it but apparently it is not possible with the firmware

Maybe this script helps:


Thanks I’ll give that a try
