Possible to set enable_query_strings in a method?

[eluser]whobutsb[/eluser]
Hello all,
I'm working with a calendar library that creates links with query strings to identify the year and the month. But it is only used on some methods in one controller. So I don't need to turn on $config['enable_query_strings'] for my entire application. I would like to be ale to set it in one or 2 methods within my code. Then when the user moves off that specific controller/method it will default back to false.

Thanks for the help!
