MipMapBias alternative for Android?

I found a an excellent solution that works right out of the box. By Correia55 https://answers.unity.com/questions/1212923/sprites-and-mip-maps-in-android-vs-ios.html

Basically Android and IOS supports MipMapBias when it goes via a custom shader. They added the MipMapBias setting to the default Sprites/Default shader. With this you simply set the bias you want in the shader properties in the editor. Very awesome!

 Shader "Sprites/Modified"
  {
      Properties
      {
          [PerRendererData] _MainTex ("Sprite Texture", 2D) = "white" {}
          _Color ("Tint", Color) = (1,1,1,1)
          _MainTexBias ("Mip Bias (-1 to 1)", float) = -0.65
          [MaterialToggle] PixelSnap ("Pixel snap", Float) = 0
      }
  
      SubShader
      {
          Tags
          { 
              "Queue"="Transparent" 
              "IgnoreProjector"="True" 
              "RenderType"="Transparent" 
              "PreviewType"="Plane"
              "CanUseSpriteAtlas"="True"
          }
