I Cannot Disable Windows Hypervisor, why?

I am trying to disable Windows Hypervisor on my computer so I can run other virtualization software like VMware or Virtual Box, but the option is grayed out in Windows Features and every command I try in PowerShell seems to fail or tells me the hypervisor is still running. I have already turned off Hyper-V, disabled Virtual Machine Platform, and checked my BIOS settings for virtualization, but whenever I run systeminfo in the command prompt, it still says "Hyper-V Requirements: A hypervisor has been detected." Has anyone found a reliable way to completely remove or disable the Windows Hypervisor without having to reinstall Windows from scratch? Any step-by-step advice would be greatly appreciated. Thank you.
