    measure = vbox, stretch = -1,
    }
  test & \begin{enumerate}
      \item test 1
      \item test 2
    \end{enumerate} \\ 
  test & test 		
\end{tblr}
\end{document}

yes, hyperref inserts an anchor and that can affect spacing. You can disable the anchor locally:

\documentclass{article}
\usepackage{tabularray}
\UseTblrLibrary{varwidth}
\usepackage{hyperref}

\begin{document}

\begin{tblr}{
    hlines,vlines,
    measure = vbox, stretch = -1,
    }
  test & \begin{enumerate}\LinkTargetOff
      \item \leavevmode\LinkTargetOn   test 1
      \item test 2
     \end{enumerate} \\ 
  test & test 		
\end{tblr}
\end{document}
