How to disable F3+B


How to disable F3+B
How can we prohibit this?


Im pretty sure you don’t… If I recall correctly that is entirely client side. I suppose you could try to force the client to have a mod blocking it, but that would be dumb.

If you don’t mind me asking why is this an issue?


Don’t know how this would work in Sponge, but there’s a vanilla gamerule reducedDebugInfo that, when set to true, stops F3+B and many other parts of the F3 menu from showing. So it’s possible, though it might affect more than you want.
