The SXA search renderings don't allow to modify the query on such a low level. If you would like to modify the query which is built you need to override
SearchService. It shouldn't be hard to do that as this service is registered in the DI container, but modifying SXA queries might not be the best idea because:
I can provide a few more examples of what can go wrong if you will modify the query build in SXA.
