How to Switch Back to Flux Mode

Hi there,
I’m wondering if it’s possible to completely turn off Hyper Realism and Nano Banana Pro. The results I’m getting with those modes aren’t great, and the best outputs I’ve ever had were with Flux. Right now it seems I can only choose between Hyper Realism and Nano Banana Pro, and I can’t switch back to Flux at all.

Is there a way to disable those modes entirely and return to Flux? Any guidance would be really appreciated!

Thanks!
