# IP: Netfilter Configuration
# CONFIG_NF_CONNTRACK_IPV4 is not set

The module is not there at all.
in "make menuconfig" you see this as:

I don't know which modules are used or required by the script/program (CSF
) you mention - I suppose it is this:
...if you happen to run a normal desktop computer or laptop - you don't need:
-programs like this
-CONNTRACK at all
for a router or server its a different story
