Unfortunately no, this is not an option when using the New Quizzes builder, which I am assuming you are using since you mentioned Stimulus questions. If you want to be able to have just an image, text, etc. and no question, you would need to use Classic Quizzes, which your institution may no longer have available.
You could work around it however with a simple multiple choice question in New Quizzes. You could include the image/slide in the question, then instruct students to select yes after they have reviewed the image, then move to the next question. You could make the question worth zero points as well to ensure students do not lose points accidentally.
