Hi&nbsp;Anonymous&nbsp;,
&nbsp;
I think you can use PowerShell to change the data source connection string in a Power BI report, but only if&nbsp; the report uses parametric connections, otherwise the change is not supported.

&nbsp;
Install the Reporting Services tool in powershell and change its parameters. Refer to the following official documentation for a detailed description of the steps.

If the problem is still not resolved, please point it out and provide related operation screenshoots. Looking forward to your feedback.
