PowerBI API DirectQuery Update Datasource

I want to update a Datasource using PowerBI API.

The datasource is from Databricks and it is using DirectQuery.
I was able to get details from the datasource, as shown belown

I've started by following this link to update the datasource:
https://learn.microsoft.com/en-us/rest/api/power-bi/datasets/update-datasources 

then I saw that it does not work for Datatabricks, so I should use the Update Parameters endpoint
https://learn.microsoft.com/en-us/rest/api/power-bi/datasets/update-parameters 

In the link it is stated that 

• DirectQuery connections are only supported with enhanced dataset metadata.
  
  
  

I can't seem to find any example of how to update the DirectQuery datasource, can someone help me?
For now I just want to change the "path" of the connection (shown in the image above), but my ultimate goal is to be able to update the connection personal access token.
