Support was so kind to answer to my email.
Thank you guys.

The sample code from this anchor helps:

Hi,

Do you mean the default input filter? Please check this file.
src/js/vendors/plugins/datatables.init.js

The default filter has been removed for our custom search filter. If you want the default filter input from Datatable, you can remove this part.

/* Set the defaults for DataTables initialisation */
$.extend( true, DataTable.defaults, {
dom: 
"<"table-responsive"tr>" +

"<"row"" + 
"<"col-sm-12 col-md-5 d-flex align-items-center justify-content-center justify-content-md-start"li>" + 
"<"col-sm-12 col-md-7 d-flex align-items-center justify-content-center justify-content-md-end"p>" +
">",

renderer: "bootstrap"
} );
