How to change the default docker registry url from nvcr.io?

Hello
The following error occurred while downloading pytorch images of nvcr from our team.
Currently, our team restricts access Chinese sites ex).cn to security issues.
Is there any way to change the download url when docker pull in nvcr.io?

$ docker pull nvcr.io/nvidia/pytorch:21.03-py3
