You just need to set the symbolizer (style) property "display" to
"none" (like in CSS).

So instead of
var symbolizer = {
    opacity: 0
}

you set

var symbolizer = {
    ...
    display: "none",
    ...
}

No other symbolizer properties will be lost (but the same is true for
your opacity hack), and the feature will not be rendered until you
delete the display property (or set it to a value other than "none").

Regards,
Andreas.
