Hi @Raph2, thanks for reaching out and taking the time to share your feedback with us! I’m afraid is currently not possible to disable certain features or options within Asana. I found a thread in our integrations category with some tips that may help you: Asana Customizations with TamperMonkey Please note we don’t support the integration since it was not developed by Asana.
I hope this helps! but please let me know if you have any other questions!
