从导航栏中删除章节页面项目符号 - beamer-Metropolis

Question

我想sectionpage = progressbar在幻灯片中添加 sectionpages ()。但是，我不希望它们出现在导航栏中。有什么办法吗？以下是 MWE：

\documentclass[xcolor={dvipsnames},compress]{beamer}
\usepackage{appendixnumberbeamer}
\usetheme[titleformat=regular, numbering=fraction, progressbar=frametitle, background=light, sectionpage=progressbar]{metropolis}           % Use metropolis theme

\useoutertheme[subsection=false]{miniframes}


\title{A minimal example}
\date{\today}
\author{John Smith}
\institute{School of something, The University of World}



%----------------------------------------------
\begin{document}
  \maketitle
  \begin{frame}{Overview}
    \tableofcontents
  \end{frame}
   
  \section{First Section}
  \begin{frame}{First Frame}
    Hello, world!
  \end{frame}

  \section{Second Section}
  \begin{frame}{Second Frame}
    \begin{itemize}
        \item option 1
        \item option 2
    \end{itemize}
  \end{frame}

  \section{Third Section}
  \begin{frame}{Third Frame}
  \only<1-2>{ % this allows to have multiple frames with only one bullet that is highlighted
    \begin{enumerate}
        \item option 1
        \item option 2
    \end{enumerate}
    \pause
  
    \begin{equation}
        f(x)=a\times x^2+b\times x +c
    \end{equation}
    }
  \end{frame}

目前，我看到的是这样的。虽然我的部分只有一个框架，但您可以在导航栏中看到两个项目符号，第一个是用于部分页面的：

其他部分页面也存在同样的问题。有什么办法可以修复吗？

你可以使用与如何从 Beamer 中的导航项目符号中删除一些页面？
