No.  But if you boot with "ipv6.disable_ipv6=3D1" then you should see

 grep . /sys/module/ipv6/parameters/disable_ipv6

returning 1.  This will be used as the default value of
"net.ipv6.conf.default.disable_ipv6" for all namespaces.  Including the
default namespace.

That's a lot of nested defaults ;-) Hope you get the meaning.
