How to disable a plugin in a specific template page

Hi all, i’m usign wordpress as csm for my projects. I use plugin like “All in One Seo Pack” for SEO titles, descriptions and keywords but i need to disable it when i load a specific template page in which i load my custom php script.

For example:
http://[MYDOMAIN]/event/
> this is a wordpress blank page
> Title: EVENT

http://[MYDOMAIN]/event/?event_id=5
> this is specific event load from a separate database.
> I want that the title will be: THE GREAT EVENT 5 (or anything else…)

Actually i have edit All In One Seo Pach core file adding a:

if (eregi(“/event/”, $_REQUEST_URI)
return;

but i’m interested in using, maybe, a hook?

Thank you a lot
