With Central NAC Pro, you should be able to do that. If you have enrolled your clients with EAP-TLS / Client Certificates, you can authenticate those without an authorization source, just on the client certificate. Also with Central NAC Pro, you can create advanced policies, like 'if issueing CA is your on-premises PKI and Client TAG or Device Type is mobile device' and apply roles or reject accordingly.
ClearPass may be the more logical choice for on-premises AD.
