Can the 23C h-Captcha security be changed to letters/numbers or will it be pictures?

Summary: In reviewing the "More Secure Career Site Experience" 23C item, it was brought to my attention that sometimes the picture captchas are not as mobile friendly for some. Is there an option to use the code like captcha where they are blurred or skewed vs. the picture option?
