Set global default value for attribute dropdowns

[mc12345678]

So to understand, you have an attribute in your attribute list that you do not want shown n(and as a side result it can not be selected)... Why is it in the attribute list to begin with then?

I think I understand now, I would say that would use javascript with an on(something) action to remove the "first" item from the dropdown... That would be something I think to add in the includes/modules/YOUR_TEMPLATE/attributes.php file when generating the dropdown information... (applying the on-click) but I could be wrong on the applicable file.)
