  • unicode-math has it. For pdflatex probably not.

  • TIL. Either I have never seen bold frak before or I did but cannot tell the difference.

For reference, the unicode-math command for bold Fraktur is \symbffrak{a}.

bold Fraktur

You have tagged the question yourself:

\documentclass{article}
\usepackage{amsmath,amssymb}
\begin{document}
$\mathfrak{abc}\boldsymbol{\mathfrak{abc}}$
\end{document}

enter image description here

Alternatively you can use \bm from the package bm.
