I am creating a book in PDF with bookdown, and I would like to change the number of the toc_depth field when converting the book to PDF. This is my _output-yml:

bookdown::gitbook:
  css: style.css
  config:
    toc:
      before: |
        <li><a href="./">A Minimal Book Example</a></li>
      after: |
        <li><a href="https://github.com/rstudio/bookdown" target="blank">Published with bookdown</a></li>
      toc_depth: 5
    download: ["pdf", "epub"]
bookdown::pdf_book:
  includes:
    in_header: preamble.tex
  latex_engine: xelatex
  citation_package: natbib
  keep_tex: yes
bookdown::epub_book: default

I added toc_depth: 5 with no results. How can I do it?

In your example you have toc_depth within the bookdown::gitbook block, which is responsible for HTML output. If you want this for PDF output, as your title suggests, you need to add it there, i.e.

bookdown::pdf_book:
  includes:
    in_header: preamble.tex
  latex_engine: xelatex
  citation_package: natbib
  keep_tex: yes
  toc_depth: 5
