Hello,
I hope this link helps: https://support.microsoft.com/en-us/windows/language-packs-for-windows-a5094319-a92d-18de-5b53-1cfc697cfca8#WindowsVersion=Windows_10
Usually, Windows 10 allows the installation directly from the Language option in the Settings. The servicing channel shouldn't affect it. If you encounter any issue with it, there may be other conditions like trying to deploy for a multiuser server or trying to enable for an enterprise.
