SP 2010: Set RSS settings for a web application with powershell

Question

PowerShell allows to set/retrieve web application settings e.g.

$webApp = Get-SPWebApplication $siteURL
$webApp.DefaultTimeZone

Will return the Default Time Zone of the web application.
I'm now looking for the RSS parameter for a web application.

RSS Settings
Specify the server-wide settings for RSS feeds. Enable RSS feeds: YES / NO

Not sure if this is possible to retrieve since it's not even listed:

$webApp.SyndicationEnabled

Answer 2

Try the following:

$webapp.SyndicationEnabled
$webapp.update()
