Not solved: VMware Workstation does not support nested virtualization on this host.

I have the latest version of VMware player (free). I have an OVA that requires VT-x/EPT and am running into this exact issue:

VMware Workstation does not support nested virtualization on this host.

I have a clean, updated version of Windows 10. I'm using the latest version of Player, Hyper-V is disabled. I see a number of people aren't having any luck on workarounds. Any updates?
