Hello,

Thank you for the clarifications.

In this case, will be better to disable this JS script for the specific product that uses the quantity functionality from the plugin with the help of the theme presets.

So please navigate to Theme Settings -> Settings Presets -> create a preset with the condition related to the specific product: https://monosnap.com/file/tGXpaxhpm1DVhILjr0S0XsoKIRtzMS

Then edit Theme Settings of this preset and navigate to Performance -> JS -> in the same field exclude the same script: https://monosnap.com/file/iJssCn5p3oj7N7rCp6ulVcaApisxxm

Here is the result: https://monosnap.com/file/O3RZLoNxqm8de8fDhj6gitdFkbLRaG

In the meantime, feel free to ask me any questions you may have.

Kind Regards
