Combining IPT and Nested Virtualization

Question

I am trying to enable IPT on a Hyper-V VM with nested virtualization, based on this article. Both the physical host and the VM are running Win11. The VM version is 10.0.

According to this note

The virtual machine generation must be 9.1 or higher. If nested virtualization is offered to the guest as well, then this needs 9.3 and up.

one can combine the two. However, whenever I try to set both, the VM fails to start.

When I try each feature individually, everything works as expected.

Is it possible to achieve that? If so, how?
