Searching for Client Side Menu Rejection

I joined a few other servers and i saw one of them have client side scripts enabled, but upon joining I was notified that I had my Lambda Menu and that I needed to remove the menu and rejoin and it kicked me. I have done some research and have not found this at all? Is there anyone that may know how to create something like this or something that will kick client with trainer and menus client side but keeping client side enabled to allow els?

Would prohibiting client and utilizing a server-sided ELS work?

We have utilized this script before, but none of the cars take damage that have stages enabled. It is also horrible on FPS drop and not optimized.
