Is there a way to install the Unreal engine from the launcher without admin privileges on a Mac

I have a lab full of Macs that had the launcher and Engine installed as an admin and then imaged, but when the users (using AD logins) login, Unreal asks for admin password to install the engine. I have tried to follow the Academic installation video, but that seems to have been posted 4 years ago and seems out of date. Is there a newer method of installation now?
