Filter packets from non-origin website

Hello. This question was previously asked on the old Q&A but left as unanswered.

When visiting most websites, the visited website will send requests to various different websites. One example of this is that google.com may send requests to www.gstatic.com. When I am using a DNS filter, these external requests show up.

I would like to filter out all packets that are not from the origin website. Currently, I am using a filter that shows all websites visited on my internet using DNS. udp.srcport eq 53 or tcp[13] eq 2 && dns.qry.name contains "www."

Is it possible to filter out these external requests with wireshark? Thank you for your time and effort.
