yes only c8i, m8i and r8i instance types support it. It is called nested virtualization[1]

Unfortunately supply is quite limited. If you want to horizontally scale on these instances you need to have a good relationship with AWS so they'll give you a big allocation before c9i is a thing.
I haven't personally tried, so I can't say for certain, but Lambda has publicly stated they run on bare metal EC2 instances, presumably the supply of whatever instance types they use should be fairly healthy
You're talking about AWS Lambda?
- Their use of bare metal isn't necessarily the latest gen hardware - AWS Lambda is part of AWS, and obviously has privileged access to supply

also i found them much less stable than metal instances running into weird kvm failures
Yes, it is. It was a challenge to make it work smooth without metal. The scaling out speed was one of the main reasons
