Can I bulk update Nodes to change an option?

I have a ton of nodes, like over 660 of them. I need to change just one option on all of them, I want to enable the "Polls" thread type. Although I can imagine other cases where some common setting might need to be changed on a lot of nodes at once.
Is there a way to bulk update the nodes with this one option change?

I've scanned over the DB a bunch of times but can't find where these options are stored.

How can I bulk update the nodes?
