If you did need to install this version of Azure SDK, you could download all the MSI files to your local and follow the instructions mentioned in the download page.
You also could execute the MSI files programmatically. Firstly We are able to use the /quiet or /qn options with msiexec to perform a silent install. Then we can use a batch file or other program languages to invoke msiexec command to install the MSI files in a loop.
msiexec /i [msi-path] /quiet /qn /norestart /log [log-path]
