How to remove headings on certain pages only?

I am trying to remove the heading on certain pages only like the appendix. Does anyone know, how to do this?

This is my code:

usepackage[utf8]{inputenc}
usepackage[headsepline,automark]{scrlayer-scrpage}
clearpairofpagestyles
ihead{rightmark}
ofoot{pagemark}
addtokomafont{pageheadfoot}{upshapebfseries}
addtokomafont{pagenumber}{bfseries}
KOMAoptions{onpsinit=setstretch{1}}
renewcommand*chaptermarkformat{}
renewcommand*chapterpagestyle{scrheadings}

title{BSP}
author{author}
date{February 2021}

begin{document}

maketitle
section{f}
.....
section{b}
.....
section{d}


end{document}
