we use kmod but that should not affect anything since it is backward
compatible with m-i-t
I think the problem here could be one of following

there is another module which is not blacklisted dependent on the
blacklisted one. In this case kmod will have to load it.

Or you have initiramfs where its getting loaded in that case you have
to modiy initramfs any changes in /etc/modules* on main rootfs won't
help.

check if feature( e.g. ipv6) is built into kernel proper and not as a
module. if its builtin then kmod won't be able to help but I guess
this you might already have verified.
