    Hi @sns ,

    The throttling feature helps to avoid performance hits in SharePoint. We can disable Throttling on SharePoint List using PowerShell

    Note: Microsoft is providing this information as a convenience to you. The sites are not controlled by Microsoft. Microsoft cannot make any representations regarding the quality, safety, or suitability of any software or information found there. Please make sure that you completely understand the risk before retrieving any suggestions from the above link.

    Use the below script to disable list throttling in SharePoint server using PowerShell:

    Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
    #Variables for Site URL and List Name
    $WebURL = ""
    $ListName = "Proposal Documents"
    #Get the Site and List objects
    $web = Get-SPWeb $WebURL
    $List = $Web.Lists[$ListName]
    #Disable throttling on the list
    $list.EnableThrottling = $false

    Find all Lists with List Throttling disabled:

    Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
    #Get All Web Applications
    $WebAppsCollection = Get-SPWebApplication
    #Array to Hold Result
    $ThrottlingLists = @()
    #Loop through each web application
    foreach($WebApp in $WebAppsCollection)
        #Loop through each site collection
        foreach($Site in $WebApp.Sites)
            #Loop through each web
            foreach($Web in $Site.AllWebs)
                Write-host "Scanning site:"$Web.URL            
                foreach($List in $Web.Lists)
                    if($list.EnableThrottling -eq $False)
                        $Result = New-Object PSObject
                        $Result | Add-Member NoteProperty Title($list.Title)
                        $Result | Add-Member NoteProperty URL($web.URL)                    
                        #Add the object with property to an Array
                        $ThrottlingLists += $Result
    Write-host "Total Number of Lists with Throttling disabled:"$ThrottlingLists.Count -f Green
    #Export the result Array to CSV file
    $ThrottlingLists | Export-CSV "c:\temp\ThrottlingListData.csv" -NoTypeInformation
