Programmatically adjusting the "toolbar type of a ListViewWebPart using Powershell script"

I have a requirement to hide new item or edit list in SharePoint list

$powershellSnapin = “Microsoft.Sharepoint.Powershell”

if ((Get-PSSnapin -Name $powershellSnapin -ErrorAction SilentlyContinue) -eq $null )

{

Add-PsSnapin $powershellSnapin

}

try

    {

        $web= Get-SPWeb "url"  #url

       $webpartmanager = $web.GetLimitedWebPartManager("/Lists/1Contracts/AllItems.aspx", [System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared) #Get the webpart manager class

        for($i=0;$i -lt $webpartmanager.WebParts.Count;$i++)  

            {

                if($webpartmanager.WebParts[$i].title -eq "1Contracts")   #list title

                    {  

                        $wp=$webpartmanager.WebParts[$i]; 

                        #$wp.ChromeType="TitleAndBorder"; #If you want to change ChromeType,Uncomment #.  

                        

                        $wp.View.Toolbar = "AllItems" #Getting view

                        [xml]$x = $wp.XmlDefinition

                        $x.View.Toolbar.Type = "None" # or Standard, Full, Freeform #Toolbar types

                        $wp.View.SetViewXml($x.view.OuterXml)

                        $wp.View.Update()

                        $webpartmanager.SaveChanges($wp);  

                        break; 

                    }

    

            }
