2017 MBA, reduce amount of shared video RAM?

[Minipudding]

I have a 13" 2017 MacBook Air (with Intel HD Graphics 6000) and it's allocating 1.5GB of my main memory for the integrated GPU. It's far more VRAM than I ever need/use, and I would prefer if I could somehow reduce the amount by perhaps 0.5GB or even more as I regularly run into RAM shortage during certain hungry tasks.

Is there any way to to modify any relevant kernel extensions to accomplish this on Mojave, or is there a way to do it on Sierra?

i think it's dynamic so will only allocate up to 1.5gb if you use it

Graphics memory is dynamically set. How do you know how much graphics memory you need? To say you could allocate better?
