[NTG-context] How to prevent sentence-case arttitle in the bibliography?

[Andreas Becker]

I seek to prevent any modification of the capitalization of article 
titles in the
bibliography. What do I need to change in the ConTeXt code to achieve 
this?
The other citation styles I tried besides APA also feature lowercasing.

I am aware of a workaround: Enclosing the capital letters in the .bib 
file with curly
brackets. However, I would prefer a method that does not involve editing 
the .bib
database.

I use Mark IV.
My approach was to edit 
/usr/share/texmf-dist/tex/context/bib/bibl-apa.tex,
however, I could not find a way to locate or modify the macro 
\insertarttitle.
