Help reducing internal solid infill

Using the recommended settings by the creator of this model, I’m supposed to use 14 grams with Bambu lab printers, there are many layers of unnecessary “internal solid infill” any help reducing this would be great.

Set bottom and top shell layers to 1. BTW 14 grams is nothing and it’s not worth sacrificing the structural integrity of the part for $0.28 in filament.
