Hello @bagdev ,
Yes you only need to override the product create pages after that in that pages put the condition for not showing your product soo you need to put
that conditioon
@if ($key != 'simple')
<option value="{{ $key }}" {{ request()->input('type') ==
$productType['key'] ? 'selected' : '' }}>
{{ $productType['name'] }}
</option
@endif
into the product create dropdown.
thanks.
