Enable billing on existing Organization in specific ResourceGroup

We are creating new Azure DevOps organization via a ARM JSON template so the billing is enabled by default and placed in a specific ResourceGroup. Now we have a DevOps organization which already exist and we want to enable billing, but not in a generic Resource Group, but in a existing resource group. I tried to use the same ARM template, but I get the error: 

TF400677: Host 1ce764d7-b085-462c-ac7c-73f303190866 does not exist. Click here for details

I tried to change the template different operationType, like Link or Create.

Is there another way to enable Billing on a existing Organization and place it in another resourcegroup?
