Disable the theme ajax search feature

Hello

A client is building a webshop and he is using the Enfold theme for that.
It’s a rather large shop and he is using the “Smart WooCommerce Search” plugin for a better search on his site.
I did not know that plugin but it seems to be very good, however, it was very very sVERY low on this specific website.

We contacted the creator of the plugin and they investigated it and now they say that it probably has something to do with the fact that there are two ajax calls for search. They ask if we can disable the theme ajax search feature to check if that can be the solution.

Now, my question is … How can I disable Enfolds ajax search feature? Do I have to comment out some code? How? And where?

Until now there is not a child theme yet. If possible my client would like to avoid that. He is using the “custom functions” plugin to add extra code to the theme. It would be nice if we can disable the ajax search feature by adding code to the “custom functions” plugin.

Thank you for the help.
