Custom shader converting to urp need help

To make that specific shader yourself:

1. Download builtin_shaders.zip file from https://unity3d.com/unity/whats-new/2020.1.1 under Additional Resource / Builtin Shaders (note unity version in the link; change to match yours)

2. Find unlit transparent cutout shader inside the zip archive file (hint: it's Unlit-AlphaTest.shader)

3. Modify that shader to suit your need

example

 Shader "Unlit/Transparent Cutout Tint" {
 Properties {
     _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
     _Color ("Tint", Color) = (1,1,1,1)
     _Cutoff ("Alpha cutoff", Range(0,1)) = 0.5
 }
 SubShader {
     Tags {"Queue"="AlphaTest" "IgnoreProjector"="True" "RenderType"="TransparentCutout"}
     LOD 100
 
     Lighting Off
