Now looked at the source, and I do not think there is a way. It might
be useful to add one, though - and might be not too hard - perhaps
something like this (didn't test):

https://gerrit.ovirt.org/89528

That said, I think it's about time we change the text(s) to imply
that we use this gateway to test network connectivity with ping,
so do not really need to be a gateway, but do need to reliably reply
to pings, and if we do have places where we use it as a gateway,
we should simply ask two questions, or at least allow overriding
in the config file.

Best regards,
