Quarto equivalent to `rmarkdown::render(params =)`

[arangaca]

Is there an equivalent in quarto::quarto_render() to rmarkdown::render(params =)? There's an execute_params argument but can't seem to make it work for that purpose:

For example, how can I pass custom parameters to the following .qmd file using quarto_render()?

```{r}
params$foo
```

execute_params is the right argument, but relies on the parameter being set with a default value in the YAML. For example, if this is document.qmd:

---
title: "Untitled"
format: html
params:
  foo: 3
---


```{r}
params$foo
```

This will work:

quarto::quarto_render("document.qmd", execute_params = list(foo = 5))

And you'll correctly get output:

params$foo
