Try this code, I have modified the custom rendering parameter like the "Ajax Options" check box.

Also Write a log on every step:-

$languages = @('en')

$startPath = '/sitecore/content/xxx/xxx/Presentation/Partial Designs/Frenchs/Recipe'

$renderingNames = @('Menu Wrapper')

$renderingParamterToUpdate = "Ajax Call"

$newRenderingParameterValue = "0"

foreach($language in $languages){

$items = Get-ChildItem -Path $startPath -Language $language -Recurse

foreach($item in $items){

Write-Host 'Updating Item: ' $item.Paths.FullPath

foreach($itemRendering in Get-Rendering -Item $item -FinalLayout) {

$renderingItem = Get-Item -Path master: -ID $itemRendering.ItemID

if($renderingNames -contains $renderingItem.Name){

Write-Host 'Found Rendering: ' $($renderingItem.Name)

$parameters = Get-RenderingParameter -Rendering $itemRendering

if($parameters[$renderingParamterToUpdate] -ne $newRenderingParameterValue){

Write-Host 'Updating' $renderingParamterToUpdate -ForegroundColor Green

$parameters[$renderingParamterToUpdate] = $newRenderingParameterValue

$itemRendering | Set-RenderingParameter -Parameter $parameters |

Set-Rendering -Item $item -FinalLayout

}

}

}

In this, the function takes as an input item you want to edit and field - either Final or Shared layout.
