Pytorch wheel package compatible with Jetson Orin

Hello;
I previously obtained torch-2.6.0+cu126-cp312-cp1312-linux_arch64.whl from the pytorch official website, but after installation, I found that it does not support the sm87 architecture; I found some wheel bags on Nvidia’s website and I have some questions:
Does the pytorch package provided by Nvidia include specialized optimizations for Jetson devices, and is its optimization non open source;
The wheel packages provided by NVIDIA are all based on Python 3.10; Why only provide Python 3.10, and where can I get the PyTorch Wheel package based on Python 3.12?
