Need help on Migrating SSRS rdl files to Power BI Service using PowerShell script

I have multiple rdl files using On-premise shared SQL db connection. My requirement is publish these rdl files into Power BI Service by changing the database connection from On-premise SQL db to Azure Serverless SQL db using PowerShell.
I have tried below PowerShell script(referred this link https://github.com/microsoft/powerbi-powershell/issues/218 ) to publish single rdl file into Power BI Service.

This script is working fine when i change the data source connection to Azure Serverless SQL db from On-premise SQL db manually opening the rdl file in Power BI Report builder and saved report locally("C:\Reports\Summary.rdl") but can't migrate with existing On-premise SQL db connection and getting below error message because Paginated Reports don't support shared data source and need to convert the connection to embedded connection.

So I need some help in below PowerShell script to change the data source connection to Azure Serverless SQL db and convert shared data source connection to embedded connection so that i can publish the report into Power BI Service.

Error Message:

{"error":{"code":"PaginatedReportAuthoringError","pbi.error":{"code":"PaginatedReportAuthoringError","parameters":{},"details":[{"code":"RdlWorkloadErrorCode"
,"detail":{"type":1,"value":"PaginatedReportAuthoringError"}},{"code":"RdlWorkloadErrorMessage","detail":{"type":1,"value":"Report contains unsupported shared data source: eton_rei_data."}}
,{"code":"PaginatedReportAuthoringError","detail":{"type":1,"value":"Report contains unsupported shared data source: eton_rei_data."}},{"code":"HostMode","detail":{"type":1,"value":"AutoPremium"}},{"code":"CapacityObjectId","detail":{"type":1,"value":"840204A1-4233-4CE6-B550-84F02691A369"}}],"exceptionCulprit":1}}}

PowerShell Script:

Connect-PowerBIServiceAccount
$token = Get-PowerBIAccessToken -AsString
$headers = @{
'Authorization' = $token
}

$path_to_rdl = "C:\Reports\Summary.rdl"
