Hi Miguel,
It depends how the conference has been set up, but in a nutshell, yes. You can normally do so by logging in, visiting your submission queue and clicking on the submission title, and visiting the review page where you'll find a field to upload a revised author version. Once the submission is accepted for presentation, however, you won't be able to upload further revisions.
Cheers,
James
