Using NGC CLI with custom CA certificates

I’m trying to use the NGC CLI behind a corporate firewall which requires TLS clients to use a custom CA certificate. Most applications automatically use the custom file /etc/ssl/certs/ca-certificates.crt but the NGC CLI does not. How can I configure the NGC CLI to use this custom CA certificate/bundle?

Here is the error that I get.

./ngc --debug registry model list nvidia/tao/pretrained_detectnet_v2:*
