Schema update through analysis services / PowerBI Premium

Hi

I have a SQL query that could is constantly changing his schema (Number of columns and column names), and Power BI service schedule refresh doesn't performe schema updates, i can only perform this update if i download the pbix and refresh it on power BI desktop. This is the standard behaviour according to the documentation bellow:

I was wondering if anyone has any ideia if there is a standard method where i could update the schema and refresh the data through XMLA or an analysis services DLL with a powershell script. 

According to my testing, when processing the partitions/tables through the diferent proceesing methods (Full, Data, Clear and recalc) i can't update the schema

Thanks in advance.
