GHE - self-signed TLS certs not reading correctly

Issue:
```
Skip_Checking
HttpError: request to {{https-api-path}} failed, reason: unable to verify the first certificate
```

Environment:
Github Enterprise Server with self-signed TLS certs.

Host machine has CA root installed and is able to read correctly if manually using `curl {{https-api-path}}`

Is there a way to supply or specify the self-signed CA root to this action?
