SharePoint Online: Change "Display Format" to Standard in the "Modified" column name

Question

There is a way, in SharePoint Online, to Change "Display Format" to Standard from "Friendly" in the "Modified" column name?

I would like do this for all sites in the tenant and for all data fields and the last but not least, for all future teams, sites and so on

Thank you

You could disable "Friendly" format in all date columns by PowerShell.

    Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
     
    #Config Parameters
    $AdminSiteURL="https://tenant-admin.sharepoint.com"
    
    #Get Credentials to connect to SharePoint Admin Center
    $Cred = Get-Credential
    
    #Connect to SharePoint Online Admin Center
    Connect-SPOService -Url $AdminSiteURL –Credential $Cred
    
    #Get All site collections
    $SiteCollections = Get-SPOSite -Limit All
    
    #Get All Webs of the Site Collection
    $WebColl = Get-SPOSite $SiteURL | Get-SPOWeb -Limit All
      
    Foreach ($Site in $SiteCollections)
    {
     Foreach($Web in $WebColl)
     {            
        #Get All Lists of the web
        $ListColl = $Web.Lists
     
        #Loop through each list 
        Foreach($List in @($ListColl))
        {             
            $ListFields = $List.Fields
            #Loop through each field
            ForEach($Field in @($ListFields))
            {
                #Get the Field to suppress "Collection was modified" Error
                $Column = $List.Fields.GetFieldByInternalName($Field.InternalName)
     
                #Pick Date Columns
                If($Column.Type -eq "DateTime")
                {     
                    #Disable Friendly Display format
                    $Column.FriendlyDisplayFormat="Disabled" #Relative
                    $Column.update()               
                }
            }
         }
      }
    }
