I founded a fast solution, for the products thats only want to pick up on the shop i put the weight at 10.000kg and in the files of the shipping modules that i want to block in the case of any of this products has in the basket i introduced this:

if ($shipping_weight >= 9999) {
} else {
return false;
}


Note: my products weight is < than 1 kg, and if any buy 10.000 products, i call he or she.....but i think that's not very probably...
