Modifying Quick View Behavior in Theme Settings – Need Help with 'Quick Add to Cart' Button

My existing “Quick Add to Cart” button also functions as a Quick View popup, blending seamlessly with our website’s style.

However, there’s an issue: when a product has no multiple variants, clicking the magnifying button directly adds it to the cart instead of displaying a popup view. I’m worried that this could deter visitors from using it for a quick product overview.

Is there a way to change this behavior in the theme settings? I’m willing to explore the CSS or theme code if a simple solution isn’t available.
