Nope. The iridium layer is ET in origin. But see, that’s not a problem for those who think bolide impacts are like getting hit in the face with a pie plate of whipped cream.

We think the Iridium is ET in origin. It is entirely possible that a volcano could have brought up the Iridium from deep sources within the Earth.

Is there some proof that the Iridium is ET in origin? Volcanoes also emit Iridium. The earth isn’t devoid of Iridium, it is just relatively rare in the crust (like most denser metals).
See Toutain, J., and Meyer, G., 1989, Iridium-bearing sublimates at the hot-spot volcano
