Bulk update for unchecked "Generate automatic URL alias" I have a lot of programmatically generated nodes with the option "Generate automatic URL alias" unchecked, so i can't use the Bulk Update of the pathauto module. 

How can i to bulk generate the pathauto alias for these nodes?

Edit: i use Drupal 7
Have you tried using Views Bulk Operation. All you will need to do is create a view that will list all the nodes that will meet your criteria and then assign an action 'Generate Url alias' (I haven't tried it though.)
