Doc generator uses wrong registry

Whenever I attempt to run `tfplugindocs generate` it assumes that my provider is under the hashicorp registry. Is there a way to pass in your own registry and provider instead of it defaulting to hashicorp?
The error I get is:
`
Error executing command: unable to generate website: exit status 1

Error: Failed to load plugin schemas

Error while loading schemas for plugin components: Failed to obtain provider
schema: Could not load the schema for provider
registry.terraform.io/hashicorp/{my_provider}: failed to instantiate provider
"registry.terraform.io/hashicorp/{my_provider}" to obtain schema: Unrecognized
remote plugin message: open : no such file or directory
`

How can I get the registry to actually use "registry.terraform.io/{my_org}/{my_provider}"
