Missing x86_64 EFI packages?

Hi all

I am just trying to move from RPi4 to a X86_64 EFI system, this one loaded with 15 Nov 2020 snapshot
But I see few packages missing, like unbound and squid
Luci app of these module just say

Packages for luci-app-squid found, but incompatible with the architectures configured

Is it just a build issue or something else?
