Is there an action hook in New Blog Templates after having the blog created in multisite?

Hi there ,

I'm working on a WP Multisite project. I need to change a site option of a newly created blog after it is created from the template. This is very important that a hook needs to run after New Blog Tempaltes does it's job since the option in question is a part of the copied template. I need to get it, change it's value and update it. Is there any hook that can do that either in New Blog Tempaltes plugin or WP itself?

Thanks and have a nice day,
