Setting up and managing device configurations using Intune
@Danylo Novohatskyi Thanks for posting in our Q&A. From your description, did you mean that you want to add different keyboard languages via intune? If there is any misunderstanding, please correct me.
Based on my research, we could refer to the following link to try to write PowerShell Scripts to add keyboard languages.

Note: Non-Microsoft link, just for the reference.
Then it is suggested to try to deploy the Powershell script via intune.
