Can you climb K2 without a permit?

I'm curious, is it really possible to attempt scaling the treacherous peak of K2 without a permit? I understand the mountain's treacherous terrain and harsh weather conditions pose significant challenges, but I'm wondering if there's a loophole or some sort of unspoken rule that allows climbers to bypass the official permit process. Is there any precedent for such a feat, or is it strictly prohibited and heavily enforced by authorities? It would be fascinating to hear your thoughts on this controversial topic.
