NASA scientists might (though I doubt it) but the Drake equation does not. It includes terms for both the chances of intelligent life developing and the chance of such life developing a technological civilization.

What the Drake equation is really trying to do is give us a rough estimate of whether there is a reasonable chance we will ever detect signals from an alien civilization; that does presuppose technology.... or aliens who communicate directly using really powerful E/M radiation.
