SAV for Linux currently cannot be managed by the SEPM, only WIndows and Mac machines.

You can install Symantec AntiVirus for Linux (SAVFL) in an environment that contains Symantec Endpoint Protection (SEP). The Symantec AntiVirus client for Linux includes real-time antivirus file protection through Auto-Protect scans and file system scans by using manual and scheduled scans. SAV for Linux clients will be unmanaged by the Symantec Endpoint Protection Manager (SEPM) because SAVFL is designed as a stand-alone product, though it is now possible to forward certain logs to the SEPM with the optional "SAVFL Reporter" module.
