FirePass SDK doesn't support pre-logon endpoint security chec

if we can't run Pre-Login Inspections against the SDK API 5.0 for Anti-Virus and Windows Information settings the can we lock it down to allow only the Firepass API? Example, we have a Pre-Login Inspector for the Firepass Stand-alone VPN client in the support documents. How about the API? This will help me write a Policy that says "Only Firepass API can log into HTTPS://Firepass.F5.com/API".
