If you wanted through normal means to turn off normalization so it would appear in traces, it would also appear that way in traces.
There is a SQL params field pack (agent extension) that will give you the information in transaction traces, it would give the actual bind values based with the connection, effectively giving you un-normalized data but really giving you more that the metrics show.
It is a supported field pack so it is something we can work on with engineering if you see issues with it.
At this stage, this sort of thing is best distributed through support cases so if you make a request for SQL Params supported field pack, it can be put onto a case for you.
