Hello. I have a GTX 1060 3gb and I only use my computer for fortnite and occasionally discord. For when I go to Settings>System>Display>Advanced Display Settings>Display Adapter properties for Display 1. It says Total Available Graphics Memory: 7158 MB and Dedicated Video Memory: 3072 MB. I was wondering how I increase the dedicated video memory so that I can get more FPS. Thanks.

You can't. How do you increase your RAM amount? You purchase RAM kits. There is no way to increase your video memory. That's integrated into your graphics card. VRAM is hardware so the user gets what they pay for and nothing more.

As stated above, you can't increase dedicated VRAM. You probably have a CPU with integrated graphics, which allocates a portion of system RAM to use as VRAM. The 7158 MB probably refers to the amount of system RAM available to use this way. The 3072 MB is the amount of VRAM on your video card, and cannot be changed.
VRAM is used primarily to hold textures. A 1080p screenbuffer (used to draw the image) is only about 8 MB, and the models used for drawing are only a few MB.
A single high-res texture (1024x1024) also includes MIP Maps (smaller versions of the texture the GPU can use when the object is far away), so is nearly 5.5 MB by itself. And if you have anisotropic filtering enabled, it can make each texture several times larger again. Since a game typically loads 100-300 textures at once, they end up eating up the vast majority of your VRAM.

This means if you ever find yourself running out of VRAM (usually shows up as stuttering as the game has to dump textures to free up VRAM, and pause while re-reading textures off disk whenever they're needed again), the solution is simple. Either turn anisotropic filtering down or off. Or bump down texture quality one notch. Each notch up or down in texture quality represents a 4x increase or decrease in the amount of VRAM used. If the game is moddable, be very judicious in your use of 2k and 4k textures. A single 4k texture with MIP maps (but no anisotropic filtering) uses over 80 MB of VRAM.
