Roblox terrain draw call optimization

I want to minimize draw calls on my game’s terrain while maintaining about the same size.

The issue: On my 3k X 2k stud island the terrain alone consumes about 500 draw calls that’s the max recommended draw calls for the ENTIRE map.

What I have tried: Looked on the dev forum and found nothing. I tried to see if the problem was with something I have done to that game specifically what I did was test the roblox baseplate and the flat terrain template. And on average (looking at first glance) the baseplate had about 30 draw calls while the flat terrain one had 300. Disabling grass only removed about 50 or so draw calls.

Even with the whole map deleted only the terrain kept draw calls still incredibely high. Deleting terrain fixes the draw calls but I am not looking forward to deleting it.
