Enable this to get AMD Secure AVIC support on guests that have this feature.

AMD Secure AVIC provides hardware acceleration for performance sensitive APIC accesses and support for managing guest owned APIC state for SEV-SNP guests. Secure AVIC does not support xAPIC mode. It has functional dependency on x2apic being enabled in the guest.
