You're gonna want a custom vLLM build.

Here's a runbook: https://github.com/local-inference-lab/rtx6kpro/blob/master/...

If the newer builds aren't working, you might try running the old v6 build (based on the eldritch-enlightenment image). gilded-gnosis gave me some problems that I haven't bothered to track down, the old builds are still gonna blow away llama-server performance. And that's before you get hooked on vLLM's PagedAttention and can run multiple sequences without a ton of extra overhead.
