Update same rendering of several templates using SPE

Question

I have a bunch of templates that have a Coveo Search Box View rendering associated with the standard values. I need to update the property "Reveal Advanced Query Suggestions" of all of them(a lot of templates in this case) and set them all to checked = false. Although I could manually update them all I'm looking for an automated way of doing such a task. Anyone have done anything similar using Sitecore PowerShell? I do have the PowerShell documentation and if I spend some time and play with it I'll figure that script on my own just wondering if anyone has ever done anything similar that they could share?

Thanks

Quick test confirms that the following allows you to set a rendering parameter on existing items.

# Path to the Coveo rendering you need to update
$rendering = Get-Item "master:\sitecore\layout\Sublayouts\Sample Sublayout"

# Update this value for the path of all the templates whose std vals you wish to update
$items = Get-ChildItem -recurse master:\sitecore\templates\Sample

$items | % {
    $renderingInstance = Get-Rendering -Item $_ -Rendering $rendering
    if ($renderingInstance) {
        Set-Rendering -Item $_ -Instance $renderingInstance -Parameter @{
            # Put new/changed rendering parameter name and value here
            # Other existing values should be unchanged by this
            "Lorem" = "Ipsum"
        }
        Write-Host "Updated $($_.Paths.FullPath)"
    }
}
