How can I get \boldsymbol to work when using the fontsetup package?

LuaLaTeX without \usepackage{fontsetup} but with \usepackage{amsmath}:

LuaLaTeX with \usepackage{fontsetup}:

I'm using the following code:

\documentclass{article}
\usepackage{fontsetup}

\begin{document}
    $x$ and $\boldsymbol{x}$
\end{document}

I've tried loading amsmath not at all as well as before an after fontsetup, but nothing worked.

You can use the \symbfit command to get bold italic math as defined in Unicode blocks.

\documentclass{article}

\usepackage{fontsetup}


\begin{document}
    (x) and (\symbfit{x})
\end{document}

fontsetup_bold_italic_x

NewCM-Book, the font which fontsetup sets by default has all the Greek and Latin uppercase and lowercase serif bold, italic and bold italic characters. You can take a look at this document for all the Unicode math available symbols.

New Computer Modern Math does not support math version=bold as far as I know. But many characters you probably need are provided. See this answer to see which fonts have boldmath coverage.
