As of ActuallyAdditions-1.12.2-r135.jar, the Lens of color can be used to get free lapis lazuli by cycling dies and bone meal.
Consider using modded dies instead of the vanilla dye item since some of them are more than just dies.

I've found no way to disable a specific lens, so I'm forced to disable all of them to address the exploit.
Is there a support with CraftTweaker for the same?

There's now a config option to allow it to look at the oredict. It's off by default.
