There is more flags that should be passed to helm fetch

--ca-file string             verify certificates of HTTPS-enabled servers using this CA bundle
--cert-file string           identify HTTPS client using this SSL certificate file
--devel                      use development versions, too. Equivalent to version '>0.0.0-0'. If --version is set, this is ignored.
--insecure-skip-tls-verify   skip tls certificate checks for the chart download
--key-file string            identify HTTPS client using this SSL key file
--keyring string             location of public keys used for verification (default "/Users/nitive/.gnupg/pubring.gpg")
--password string            chart repository password where to locate the requested chart
--repo string                chart repository url where to locate the requested chart
--username string            chart repository username where to locate the requested chart
--verify                     verify the package before using it
--version string             specify the exact chart version to use. If this is not specified, the latest version is used
--repository-cache string    path to the file containing cached repository indexes (default "/Users/nitive/Library/Caches/helm/repository")
--registry-config string     path to the registry config file (default "/Users/nitive/Library/Preferences/helm/registry.json")

Two last options are global not only for fetch sub-command

--repository-cache string    path to the file containing cached repository indexes (default "/Users/nitive/Library/Caches/helm/repository")
--registry-config string     path to the registry config file (default "/Users/nitive/Library/Preferences/helm/registry.json")

That's right but they must be passed to fetch command otherwise it won't work as expected

$ helm repo add my-repo https://charts.helm.sh/stable --registry-config ./config
