Change color of beamer presentation background - R Markdown

I am trying to change the background color of my beamer presentation in R Markdown, but I only want to change the background color of the cover page, but when I insert the following code, the background color change is produced for the whole presentation.

I would appreciate if you could help me with my query.

title: "Titulo"
subtitle: "Subtitulo"
author: "Nombre"
date: "2023-07-10"
output:
  beamer_presentation:
    incremental: true
    theme: "Rochester"
    colortheme: "default"
    fonttheme: "structurebold"
    toc: false
    slide_level: 3
    keep_tex: true
header-includes:
  - \usepackage{ragged2e}
  - \usepackage{color}
  - \usepackage{listings}
  - \AtBeginSubsection{}
  - \titlegraphic{\includegraphics[width = 3cm]{logo}}
  - \setbeamercolor{background canvas}{bg=red}
