What are the actual usage of Hyper-v for docker desktop on windows?

Hello,

I have switched to windows container on docker desktop and have disabled Hyper-v which is required for Linux container.

Q1: my question is can i run docker with windows container without Hyper-v. or is it required to enable hyper-v for windows container as well on docker desktop?

Q2: In short does docker desktop-ce need hyper-v enabled ,no matter is it a Linux or windows container?

Q2.1: If so, what are the actual usage of hyper-v for docker desktop windows?

FYI:
I am using
docker version:2.2.1.0
channel :edge
docker engine : 19.03.5
windows version: windows 10 pro
