you can use \@ifpackageloaded{graphicx} for test of its presence. The
full configuration file is bellow:
-----------------------
\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\makeatletter
\@ifpackageloaded{graphicx}{%
\DeclareGraphicsExtensions{.svg,.png}
%this below to make it resize the SVG image, if it is there, to
%what is in the includegraphics.
%thanks to @Michal.h21 for this trick
\newcommand\emwidth{10}
\newcommand\CalcRem[1]{\strip@pt\dimexpr(#1)/\emwidth}
\Configure{graphics*}
{svg}
{\Picture[pict]{\csname Gin@base\endcsname.svg
\space style="width:\CalcRem{\Gin@req@width}em;"
}%
\special{t4ht+@File: \csname Gin@base\endcsname.svg}
}
}{}
\makeatother
\Configure{Picture}{.svg}
\begin{document}
\edef\mymathjaxconf{\detokenize{MathJax.Hub.Config({
TeX: {
MAXBUFFER: 40*1024,
Macros : {
relax: "{}",
setlength: ["{}", 2],
allowbreak: "{}",
}},
});}}
\ExplSyntaxOn
\regex_replace_all:nnN{ \x{23}\x{23}}{\x{23}}{\mymathjaxconf}
\ExplSyntaxOff
\Configure{@HEAD}{\HCode{<script

\EndPreamble
