AMD nested virtualization

Hello I am attempting to get SVM enabled in my Windows guest to improve hyper-v performance on my AMD Ryzen 5900x. Below is my XML config. With these options Coreinfo64 does not detect SVM being enabled in Windows 11 guest. @jonp I have enabled nested kvm and modprobe returns it is enabled. Did we ever figure out how to get nested working on Unraid?
