How to update just PyTorch

I am trying to test the AI solution SimSwap however when I used their guideline using
" ```
conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cudatoolkit=10.2 -c pytorch

I am getting "NVIDIA GeForce RTX 4080 with CUDA capability sm_89 is not compatible with the current PyTorch installation.
The current PyTorch install supports CUDA capabilities sm_37 sm_50 sm_60 sm_61 sm_70 sm_75 compute_37.
If you want to use the NVIDIA GeForce RTX 4080 GPU with PyTorch, please check the instructions at https://pytorch.org/get-started/locally/"
  when trying t fix it I updated the [PyTorch ](https://discuss.pytorch.org/t/geforce-rtx-3090-with-cuda-capability-sm-86-is-not-compatible-with-the-current-pytorch-installation/123499)
trying to fix it using "conda install pytorch torchvision torchaudio pytorch-cuda=11.6 -c pytorch -c nvidia" seem to miss up other related package any suggestion how to update just PyTorch

You would have to install the latest PyTorch release with a CUDA 11.x runtime to be able to run code on your sm_89 GPU.
