Hello,
I have been following the documentation here for custom message and cache relays, however the options don't exist:
Installer command-line options for Linux - Sophos Central Admin

You've provided the instructions to reset Sophos for golden images for windows on the new Sophos-spl agent, but not for Linux. We need instructions to prepare images for Linux. The legacy sav-protect agent has instructions to do this.
