We do not have lightweight VPN only client for Mac, AFAIK. EPS package includes FDE, FW, malware protection, emulation, anti-ransomware, and more. Most of this components require system level access.
You may want to try SNX/Mobile Portal option instead.
The mentioned scripts and more, they are under Library, Application Support, in the client package folder. If you do not know where it is, you probably should not poke around.
Once more, I emphasise, off-loading and re-loading components is a very bad security practice, and I would urge you not to do that on production machines.
