Please provide a new command line parameter to output tikz without the latex preamble

I'm trying to include UML diagrams in org mode beamer (latex) exported documents. The current -tlatex flag outputs a full latex file (i.e., documentclass, usepackage, begin{document} ...) all of those mess up my actual document that this tikz output is being included within.

Please can you provide a new command line parameter to output tikz without the latex preamble.
