Mostly the same as you did.
I also added the kvm code under features.
Although I read that it gives some people lag. I've not tried it without this code.
<kvm>
<hidden state='on'/>
</kvm>
I've changed my PC name from something like "DESKTOP-R29JE8" to a different name.
For the Hyper-V part I've deleted the whole section in the XML instead of in the form view. But I can't imagine that making a difference.
Hope any of this helps! And I truly hope anti-cheat engines will chill with the banning of VM's.
I'm quite new to Unraid and VM's myself, so I'm afraid I won't be able to help you any further if this doesn't work for you.
Good luck!
