Access FMX TListView TListViewItem

Question

Is there a way to access the different items configured to a FMX TListview's ListViewItem component below the ListView rows are filled?

I have a TListView set to DynamicAppearance and have it set up as shown in the image below.

Based on a field in a database, I need to make some of the Items under columns 1 to 9 invisible. I have been able to make this work using the code below within the UpdateObjects event, but was wondering if there is any way I can accomplish the same thing when the database is open, instead of when each ListViewItem is updated.

procedure TfrmHistoryRuntime.ListView1UpdateObjects(const Sender: TObject; const AItem: TListViewItem);
begin
  Drawable := TListItemText(AItem.View.FindDrawable('DateTime'));
  if assigned(Drawable) then
    Drawable.Height := 52;
  AItem.Height := 54;

  for I := 1 to 9 do
    begin
      Drawable := TListItemText(AItem.View.FindDrawable('Device' + IntToStr(I)));
      if assigned(Drawable) then
        Drawable.Visible := IsBitSet(fGroups, I);
      Drawable := TListItemText(AItem.View.FindDrawable('Real' + IntToStr(I)));
      if assigned(Drawable) then
       Drawable.Visible := IsBitSet(fGroups, I);
    end;
end;

I did figure out I can access the items using code similar to below, but don't know if there is a way to set the index value using the Item name and not a number (which might change)?

  ListView1.ItemAppearanceObjects.ItemObjects.Objects[0].Height := 52;
  ListView1.ItemAppearance.ItemHeight := 54;
  ListView1.ItemAppearanceObjects.ItemObjects.Objects[2].Visible := false;
  ListView1.ItemAppearanceObjects.ItemObjects.Objects[12].Visible := false;
