Windows 11 Memory Integrity

Hello, I was wondering if anyone could help me get memory integrity turned on? I have a custom built pc and am running the latest beta release from windows insider program. I have tpm 2.0 and secure boot turned on. I keep getting a message that memory integrity is not on and when I click on it, it says standard hardware security not supported. I have watched several YouTube videos and tried several fixes, but no luck. Any ideas? Thank you!
