the following search string
( app eq dns ) and ( port.dst eq 53 ) and ( addr.dst in 8.8.8.8 )
searches and displays all dns traffic using port 53 that has the destination ip of 8.8.8.8
I would like to know if I can look at all dns traffic traveling on port 53 except the traffic going to 8.8.8.8

In the filter, you can modify it as ( app eq dns ) and ( port.dst eq 53 ) and ( addr.dst notin 8.8.8.8 ).
This helps in filtering the dns traffic excluding the traffic going to 8.8.8.8.
Hope this helps.

adding to what @atluri4b8 already said you can also use a bang
!(addr.dst in 8.8.8.8) will exclude 8.8.8.8
