How to Disable Beta AI Infographics Feature in Gamma API Presentation Generation

Hi, we are currently using the Gamma api to generate presentations. We currrently pass the following parameters: tone, themeId, audience, exportAs, numCards, textMode, textAmount, imageSource, cardDimensions, additionalInstructions, inputText. Since recently, the presentations we've been generating for our customers who have their own gamma theme ids (with their own accent images, etc) have been generating these in the slides:(first image) These look off brand for our customers. I did a bit of digging and found that these are being generated by the BETA AI infographics feature. We want to turn this off for our generations, and I was wondering what the best way is. Is it including instrucions in the additionalInstructions block? Or is there a deterministic way to prevent using this?
