Hi @Sivasankar Rebba ,
I'm not familiar with PowerShell, here is a same thread you may take a reference to.
Someone also give a sample like shown below.
"C:\Program Files\Microsoft SQL Server\130\DTS\Binn\DTExec.exe"
/project "E:\...\bin\Development\Packages.ispac"
/package "Package1.dtsx"
/SET \Package.Variables[$Project::Target_ConnectionString];\""Data Source=MyServer\InstanceName;Initial Catalog=My_New_DB_Name;Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;"\"
