我永远不会这样做，但如果你坚持的话，你可以破解类似的东西：

\documentclass[%
    a4paper,% not needed because default       
    oneside,        
    12pt,               
    onecolumn,          
    openright,% nonsense after oneside or before openay
    openany,% nonsense after onecolumn
    parskip=full*,      
    headsepline,        
    footsepline,        
    bibliography=totoc,
]{scrbook}
\usepackage[T1]{fontenc}

\usepackage[utf8]{inputenc}

    ]{geometry}

\usepackage{scrlayer-scrpage}
\renewcommand*\chapterpagestyle{scrheadings}% not recommended
\renewcommand*\sectionmark[1]{\markright{\makebox[0.8cm][l]{\thesection}\ #1}}

\usepackage{blindtext}

  \edef\reserved@a{\thefooternote}%

\newcommand*{\showfooternotes}{%

  \smash{\parbox[t]{.9\linewidth}{\footernotes}%

有了这些非常简单的建议，可能会产生其他不良影响，例如在脚注标记之前的页面上出现脚注。再说一遍：我永远不会使用它。
