Thank you for providing the additional details above.
Currently there is no Azure CLI or PowerShell command available to list the regions where network watcher can be enabled. This is the list of Azure regions where Network watcher can be enabled.
You can enable Azure Network Watcher in every region available via portal instead by following the steps below.
- Go to portal.azure.com and search for Network Watcher as shown below.
- On the Network Watcher window click Add.
- Select your subscription and it will list the available regions where you can enable Network watcher , click select all and then Add. (if the list is empty then that means you have already enabled Network Watcher for all available regions)
If it is possible, can you please send me the link for Azure CIS 2.0.0 documentation you are following? I will check if we can add the information above.
Hope this helps! Please let me know if you have any additional questions. Thank you!
