Remove the query string

Hi

Thanks for the wonderful theme. I am going to launch my new site with it. But some problems are showing up in regards to SEO. May you please help by telling me how to Remove query strings from static resources. I have tried a lot but haven’t been able to find out any clue. Because of dynamic URL’s my SEO report isn’t going fine. Here is the GTMetrix report URL of my site https://gtmetrix.com/reports/fastwp.tk/SI1i3o8g.
