Hello, I own an HP ZBook Power 16-inch G11 Workstation (Product ID: A3YS5ET#BED) running BIOS version HP W97 01.06.01 (2025-04-23). I am experiencing an issue where the system firmware continuously forces the Windows hypervisor (Hyper-V) to remain active, even after disabling Hyper-V features in Windows, turning off VBS/Memory Integrity, clearing the TPM, restoring factory security defaults, and disabling all related BIOS security settings (Virtualization-Based Security, Sure Start, Secure VM Mode, VT-d, etc.).

Despite all attempts, msinfo32 always reports: “A hypervisor has been detected,” and VMware Workstation Pro cannot access Intel VT-x exclusively, which prevents running older guest OSes such as Windows XP. It appears that the BIOS is enforcing hypervisor activation at the firmware level, and there is no option exposed to disable this behavior. Could you please confirm whether this model and BIOS version allow Hypervisor OFF / VT-x exclusive mode, and if not, whether a BIOS update, rollback, or enterprise lock removal procedure is available to restore full VT-x functionality for non-Hyper-V hypervisors such as VMware Workstation?
