Knit only until a specific chunk

Is there a way to knit a html_document until a specific chunk?

Suppose I have this .Rmd and I want only to knit a html_document until the cars chunk:

---
title: "Untitled"
author: "Igor Kuivjogi Fernandes"
date: "14/02/2020"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)

R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)

Including Plots

You can also embed plots, for example:

plot(pressure)

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

In case someone lands here. You can check here for a very clear solution. https://bookdown.org/yihui/rmarkdown-cookbook/knit-exit.html

knitr::knit_exit() is what you probably what you're looking for.

This

---
title: "Test"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r cars}
summary(cars)
```

```{r pressure, echo=FALSE}
plot(pressure)
```

produces this:

And if you add one chunk that controls the global options...

---
title: "Test"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r cars}
summary(cars)
```

```{r setup2, include=FALSE}
knitr::opts_chunk$set(eval = FALSE)
```

```{r pressure, echo=FALSE}
plot(pressure)
```

...then the last code chunk is not executed and there is not plot:

I find a way, but isn't so pretty. I have selected all the code and pressed Ctrl + Shift + C, so commented all the lines:

---
title: "Untitled"
author: "Igor Kuivjogi Fernandes"
date: "14/02/2020"
output: html_document
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
