Hi,
Searching the Internet, I have found a solution for my problem.
Install packages {extrafont} and {extrafontdb}
Download and install the new fonts.
In RStudio IDE in R, register the new fonts only once:
extrafont::font_import()
extrafont::loadfonts(device="win")
In the Quarto document, in the first R-chunk add:
library(extrafont)
