@BAAAASS : Please read the article thoroughly. The article explicitly says this:
Data modeling limitations
All Tabular Object Model (TOM) metadata can be accessed for read-only. Write operations are limited because Power BI Desktop must remain in-sync with the external modifications, therefore the following operations are not supported:
