Hopefully somebody else will answer with a proper org solution but, in
the absence of anything else, you could wrap the LaTeX code in the
latex_header with an \if looking for something that is unique to beamer
and only include the code if not beamer.  Something along the lines of

#+latex_header: \ifx\frametitle\undefined\usepackage{somepackage}\fi

which seems to work.  \usepackage{somepackage} is what you actually want
when not using beamer.  Replace with your own stuff.  You can make it
more readable by doing:

# only for LaTeX and not beamer
#+latex_header: \ifx\frametitle\undefined
#+latex_header: \usepackage{somepackage}
#+latex_header: \usepackage{another}
#+latex_header: \fi
