Hi there, unfortunately you cannot disable notifications for a specific project. Notifications are basically related to activities around interaction with collaborators on files or projects such as comments, requests and so on. You can reduce notifications if you feel too many notifications from setting: https://help.figma.com/hc/en-us/articles/360039813234-Manage-notification-preferences

I know this is not the best solution for you but I hope this information helps a little bit.

Thanks,
