Let’s assume you want to hide all object properties that have no value (are empty). Here is a simple approach:

# get any object
$object = Get-Process -Id $pid

# try and access the PSObject
$propNames = $object.PSObject.Properties.Where{$null -ne $_.Value}.Name
$object | Select-Object -Property $propNames

This will output only the properties that have a value. You could even make sure the properties are sorted:

# get any object
$object = Get-Process -Id $pid

# try and access the PSObject
$propNames = $object.PSObject.Properties.Where{$null -ne $_.Value}.Name | Sort-Object
$object | Select-Object -Property $propNames
