Disabling a built-in recipe results in lots of errors being thrown like the following:

[09:43:25] [Server thread/ERROR] [FML]: Parsing error loading built-in advancement ic2:recipes/dusttin_recipes
com.google.gson.JsonSyntaxException: Unknown recipe 'ic2:shapeless_item.itemdustbronze_-364730307'

Would it be possible to either add support for disabling IC2's advancements, or having it detect that a recipe is disabled and not add the advancements relating to those items?

Unfortunately in 1.12.2 there seemingly isn't a good way to modify or disable modded advancements. Since the prerequisuite recipe IDs seem hardcoded, I can't even replace a recipe with a different one and have the advancements work.
