Cisco ASA 5555-X AnyConnect using Duo SSO and using Client Cert

[Elude]

I have a Cisco ASA 5555-X. Uppers are asking for me to configure ASA AnyConnect using SAML. I am using Cisco Duo as my MFA and I also have Cisco Duo configured as my SSO using Azure as my Authentication Source. On the ASA I have the Authentication pointed to SAML. My question...is there a way to configure the ASA to use both SAML and Client Cert for Authentication?

Certificate and SAML for Authentication is supported in ASA 9.18(1)+ and FTD 7.2.0+. That means that you won't be able to achieve it on ASA 5555-X as it does not support anything newer than 9.14.4.
