How to Import particle material with color ramp in Unity

Hello Expert,

I made a Blender Guru famous donut. When I tried to export this into Unity I found a trouble with the sprinkles. 1. I can't find the way to baked a material with color ramp for the random color to Uniy. 2. I tried to make all particles individual, but its no way to import 500+ particles' textures here....

Any one have a good solution if I want to make such colorful sprinkles in Unity?? I'm trying to find the solution from Unity or Blender sides.....
