There possible some Bios setting, I know there is a software the Nvidia has for their GPU that allow you to control the settings which is this https://www.nvidia.com/en-us/geforce/geforce-ex... but outside of that not really your either buy a new GPU or in your case a new laptop is the GPU is not imbedded on the Mobo. The reddit link I sent also explain it as well even though it talk about the integrated on it applies to the Nvidia one as well. You can also in crease the ram as well
this should also explain the Nvidia side of it even though it might not be your GPU but the process is the same https://www.nvidia.com/en-us/geforce/forums/gef...
I really boils down to increase ram, get a new GPU( its a laptop so really can't) or get a new laptop or purchase a desktop that allow you to swap GPU easy. Dependent on what you change can cause more harm that good
