I'm trying to increase performance on through pandoc Rmarkdown

Question

I'm trying to tweak pandoc parameters to increase memory and conversion speed, but can't get anything. This is the ouput part in the RMarkdown:

output:
  word_document: 
    toc: yes
    pandoc_args: ["-RTS", "-M2G"]
    fig_width: 8
  html_document:
    self_contained: no
    keep_md: no
    pandoc_args:
    - "-RTS"
    - "-M2G"
    - "--to=html5"
    toc: yes
    toc_float: yes
    collapsed: no
    smooth_scroll: yes
    theme: cosmo
    number_sections: yes
    cache: yes
    fig_width: 8
    df_print: kable
editor_options:
  chunk_output_type: console

I've beeing trying to export to .html and it took hours to render it. Now I'm trying to export it to word but still the same...it works but it takes a lot of time. I'm trying to tweak pandoc arguments but can't get this done. Here is the message while rendering...

/usr/lib/rstudio-server/bin/quarto/bin/tools/pandoc +RTS -K512m -RTS Proceso_NETO.knit.md --to docx --from markdown+autolink_bare_uris+tex_math_single_backslash --output Proceso_NETO.docx --lua-filter /home/cesarkero/R/x86_64-pc-linux-gnu-library/4.3/rmarkdown/rmarkdown/lua/pagebreak.lua --table-of-contents --toc-depth 3 --highlight-style tango -RTS -M2G 

How can I really change those pandoc_args while doing knitr ? There is something else I can change to increase pandoc conversion from .md to .docx or .html ?

Run-time-system arguments need to be wrapped by +RTS and -RTS (docs). So, for example

output:
  word_document: 
    pandoc_args: ["+RTS", "-M2G", "-RTS"]

But a conversion taking that long is likely suffering from problems that are difficult to fix in this way.
