Using JavaScript's Selenium Webdriver, how to launch Chrome with a specific path to chromedriver.exe?

Question

I have the following Javascript code that launches Chrome with the path to chromedriver.exe specified by the PATH environment variable. This question is different than how to launch Chrome with a specific chrome.exe because chromedriver.exe is a standalone server that takes in commands from Selenium Server and uses JSON commands to talk to the Chrome browser's API. You need both chrome.exe and chromedriver.exe to launch a Chrome browser with Selenium.

    let driver = await new Builder()
        .forBrowser('chrome')
        .build();

However, I would like to clear my PATH environment variable and instead set a path from within the code that launches Chrome, something like the below. How can I do that please?

    let driver = await new Builder()
        .forBrowser('chrome')
        .withDriverPath('C:\\temp\\chromedriver.exe')
        .build();

It seem posible to set in your environ variables a value for CHROMEDRIVER_EXE
