Why doesn't Sophos XG Software support EFI-Boot?

Hi all,

I recently bought a new server for my SophosXG which I run at home. Unfortunately I did forget that SophosXG still does not support EFI boot, so I did not think about that when purchasing the server. So now, because the device only supports EFI-Boot, and no legacy boot (aka CSM) I am left with the pretty unsatisfying situation that I have to run a Hypervisor on my new server to run the XG on it and sacrifice much simplicity and some performance. 

I mean yes, I do understand that it does not support EFI boot, but why?

Firstly even open source firewalling solutions like OPNSense or pfSense are able to boot on EFI only systems. Furthermore - as touched on in this old thread - XG's underlying OS has even been switched to Ubuntu/Debian in XG Version 18 . Those two Linux distributions themselves support EFI boot for an eternity now.

Can someone, maybe from Sophos directly, elaborate on the "why"? I really struggle trying to understand what might be the reasons not to support EFI boot in 2024.

Best Regards
