There are people doing vegan keto. It is theoretically possible.

I imagine it is the most boring diet in the world though. :)

From what I've heard vegetarian Keto isn't too bad.

I'd worry about getting healthy oils on a vegan keto diet, healthy vegetable oils get expensive very fast. Most keto diets don't pay much attention to fat sources, but while lots of canola oil technically meets the macros, it'd not be healthy at all...
