But if visual after DA/DH you are no longer using the ILS, unless you have helicopters fitted with auto-land, which I don't think currently exist. The A109S certainly doesn't have that facility.
Absent a limitation, why decouple simply because the runway environment is in sight? Especially in low IFR conditions.
