Certificate based authentication - ARO + Azure AD

While configuring AAD with ARO, today we have the option to use a password as a secret for the AppRegistration described [here ](https://learn.microsoft.com/en-us/azure/openshift/configure-azure-ad-cli)
Reading through the docs, it's unclear which switch to use to associate the certificate while creating the OpenShift secret.

```
oc create secret generic openid-client-secret-azuread \
--namespace openshift-config \
--from-literal=clientSecret=$client_secret
```

Is there a plan to document the guidance for "certificate based authentication" described [here](https://learn.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal#option-1-recommended-upload-a-trusted-certificate-issued-by-a-certificate-authority)?
