Windows 10 Google Chrome and GPOs

Hi,

Bear with me if this is question should be on Google forum instead of Microsoft forum.

https://docs.microsoft.com/en-us/microsoftsearch/set-default-homepage#:~:text=Navigate%20to%20%3CComputer%2FUser%20Configuration,and%20set%20it%20to%20Enabled.

According to above MS document, Google Chrome home page can set via additional Group Policies. Is it ONLY true for domain joined devices? Because on workgroup, I am failed to set the customization.

Another reading (non-Microsoft) describes the same procedure, but can we make it via Local Group Policy for non-domain joined devices.
