Hi Klaus
This will be possible in 8.3.0 (ready later today, if all goes to plan) using the OnIncludeLayer event.
// Exclude masks from view
function TMyForm.IELayerMView1IncludeLayer(Sender: TObject; LayerIndex: integer; Layer: TIELayer; var Include: Boolean);
begin
if Layer.IsMask = False then
Include := False;
end;
