The Ruby selenium-webdriver API doesn't expose a separate Chrome options object like Java/Python but you can set the options via "Capabilities".

The Capabilities web page provides a Ruby example and the table of recognized capabilities that you can inject. Plugging those together with excludeSwitches:

caps = Selenium::WebDriver::Remote::Capabilities.chrome("chromeOptions" => {"excludeSwitches" => [ "--ignore-certificate-errors" ]})
driver = Selenium::WebDriver.for :chrome, desired_capabilities: caps

Take a look at Watir too, it's a front end for WebDriver.
Their examples show how you can send a :switches array which is passed straight through to the web driver so you can do the same. That makes adding other switches a bit easier rather than going through capabilities.

There is a chromedriver issue on the topic as well. There are posts detailing that you can add a --test-type argument to work around the certificate issue and ruby code examples like above.

Why Vertical Text Orientation Is A Nightmare For Cross Browser Compatibility?

The necessity for vertical text-orientation might not seem evident at first and its use rather limited solely as a design aspect for web pages. However, many Asian languages like Mandarin or Japanese scripts can be written vertically, flowing from right to left or in case of Mongolian left to right. In such languages, even though the block-flow direction is sideways either left to right or right to left, letters or characters in a line flow vertically from top to bottom. Another common use of vertical text-orientation can be in table headers. This is where text-orientation property becomes indispensable.
