Would is be possible to make the admin only option for the infinity upgrade a configuration that can be toggled? Using it in my pack as a creative craft and worried it may cause some issues on a server if people are not OP.

We have a discussion on potential config / options to allow survival players to use it (set items / break blocks with it). Could you describe the use case you're thinking of?

I have a recipe in my mod pack I'm developing where the player can make it as an endgame item to get infinite items.

I have added a survival version of this upgrade in one of the latest versions which should do what you were looking for
