Detectron2 needs Cuda max 11.3 Version

Hi guys

we just installed a new RTX3070. Distribution is Ubuntu 18.04 LTS.
The driver installation was successful with the latest driver 510.47.03.
Unfortunetly the cuda version is 11.6. It is not compatible with detectron 2 installation.
Pytorch 1.10 is requested and max cuda version 11.3.
I am not able to downgrade the version to 11.3.
Installation of an older driver did not work. Only cuda installation did not work either.
Please give some installation hints how to downgrade the cuda version.
