Why is Chromium blocking DefaultSearchProviderEnabled Group policy?

Question

I am trying to change the DefaultSearchProvider of Chromium browser using the group policies. I followed https://chromium.org/administrators/policy-list-3#DefaultSearchProviderEnabled this documentation. I can see the policies in chrome://policy/ but the problem is that the DefaultSearchProviderEnabled is being blocked by Chrome and I am getting an error message:

This policy is blocked, its value will be ignored.

I have attached the screenshots of my group policy Registry keys and chrome://policy page. Please tell me if I am doing anything wrong?

I am using Chromium version: 78.0.3875.0

You are need Windows Server for that. It is for security.
