Debian 12 cudnn libraries missing in repo

We are preparing our data center for the upgrade to Debian 12 bookworm.
Some of our scientists require cudnn, which is currently missing in the repo: Index of /compute/cuda/repos/debian12/x86_64
Debian 12 is also not listed here: Installing cuDNN on Linux — NVIDIA cuDNN 9.0.0 documentation

Is there any information when it will be available or why it is missing?
