Deploy Key Vault Certificate for App Registration via Intune

Hi All,

As the title suggests, I have an App Registration that is using a certificate generated from Azure Key Vault. After testing, it seems that the script using the App Reg will only authenticate if the certificate is stored via the pfx format, not the cer. I have tried to deploy the pfx certificate using the PKCS config profile template in Intune but it failed (with no error message given). Has anyone else tried deploying pfx certificates from Key Vault via Intune?
