How to modify a custom property for multiple nodes with Powershell

So, 

I have been working on several  powershell scripts...  Here is what i have.

# Be sure to install the SwisPowershell module on Powershell 5 or lower prior to use
# Install-Module SwisPowershell

#Designate Hostname

$server = 'host'

$creds = Get-Credential

$swis = Connect-Swis -HostName $server -Credential $creds

#$nodes = Get-SwisData $swis 'SELECT NodeID, Caption, DNS, IPAddress, Uri FROM Orion.Nodes'

## Export data from SWQL and arrange it in Excel first
## CSV Import Approach
$updates = Import-Csv C:\Users\list.csv

foreach ($update in $updates)
    {
        Write-Host "Updating"$($update.IPAddress)"@"$($update.Uri)
        $properties = ''
        $properties = $update.psobject.properties | where-object {($_.Name -ne "Uri") -and ($_.Name -ne "NodeID") -and ($_.Name -ne "IPAddress")}

        $record = @{}
        foreach ($property in $properties)
            {
                if (($($property.Value) -ne $null) -and ($($property.Value) -ne ''))
                    {
                        $record += @{$($property.Name)=$($property.Value)}
                    }
            }

        Set-SwisObject $swis -Uri $($update.Uri) -properties $record
    
    }

i have a custom property 'NodesCustomProperties.ServiceNow_Owner_1'

how would i be able to use a serverlist.csv, to modify all servers in the list...and modify the custom property above?
