Unwanted message in flexdashboard from sf

Question

The use of sf::st_write(...) in my flexdashboard through:

```{r,message=FALSE,warning = FALSE}
st_write(SPDF_sf_2154, here("geo","pts2154_2.shp"), append=FALSE)
```

causes unwanted message in the html output, like:

    Deleting layer `pts2154_2' using driver `ESRI Shapefile'
Writing layer `pts2154_2' to data source 
  `/Users/tristanlorino/Nextcloud/SonoRezé/Documents de travail/Analyse-R/Sonoreze/geo/pts2154_2.shp' using driver `ESRI Shapefile'
Writing 228000 features with 5 fields and geometry type Point.

How can I avoid it?

Thanx, Tristan
