uses
  CommCtrl;

procedure TForm1.DateTimePicker1DropDown(Sender: TObject);
var
  wnd: HWND;
  Style: Integer;
begin
  wnd := DateTime_GetMonthCal(DateTimePicker1.Handle);
  if wnd <> 0 then
  begin
    Style := GetWindowLong(wnd, GWL_STYLE);
    SetWindowLong(wnd, GWL_STYLE, Style or MCS_NOTODAY or MCS_NOTODAYCIRCLE);

  The calendar will still highlite the current day but the circle and the
  today display at the bottom are gone.
