How disable the photo confirmation

Hello,I want use reCaptcha v2 in an project for a credit company.But it is not good for branding to ask "Where are the beer" or "Where are the cat" in the six images ...Can we turn off the forced checking with the images and ask only write captcha when verification is not sufficient?Thanks -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
