Disable autocomplete on specific exposed filter

When we use an exposed filter (fullxtext field) on different places, all the fields render autocomplete functionnality. I need to disable the autocomplete behavior on a use case.

My views search exposes the fulltext field in a block. This block is rendered inside the header on my site and in the views search page. On the search page, I need to disable the autocomplete behavior. In the settings on this module, I can't disable this functionnality on this specific case.

Is there a solution, with a custom code, to achieve this?

Thanks for your help.
