Terrain resolution with distance

Hello...

I have this issue with unity terrain. It has pretty smart resolution system that lowers the resolution based not only on a distance, but also based on the "roughness" of the terrain, apparently. Thas is cool most of the time, but I dont want it.

What I would like is to have a terrain resolution based only on a distance. And fairly agressive = 512 at players location, but 64 after ~1000 units.
