Good afternoon!
How to make an exception if the user registers by filling in the fields in the order on the checkout page

//создаём профиль
      //PERSON_TYPE_ID - идентификатор типа плательщика, для которого создаётся профиль
      $arProfileFields = array(
         "USER_ID" => $arFields['ID'],
   "NAME" => $arFields['NAME'],
         "PERSON_TYPE_ID" => 1
      );
    { 
  
   $PROFILE_ID = CSaleOrderUserProps::Add($arProfileFields);
      
      //если профиль создан
перед  $PROFILE_ID = CSaleOrderUserProps::Add($arProfileFields);

it is necessary to set the condition that if the user already has a delivery profile, then do not create it,
how can this be implemented?

I didn’t quite understand the question, but ...
1. Save the necessary things at the stage you need (in session data, for example)
2. Do a check in the registration / checkout component
