Can someone add (or help me add) a wind effect to my current shader?

Question

So I slightly modified the specular shader so that it has culling off and I want to add in something to make it wave. Pretty much something like this https://forum.unity3d.com/threads/shader-moving-trees-grass-in-wind-outside-of-terrain.230911/.

Shader "TheHyperChimp_Asset_Pack/UberShaderCullOff" { Properties { _Color("Color", Color) = (1,1,1,1) _MainTex("Albedo", 2D) = "white" {}

     _Cutoff("Alpha Cutoff", Range(0.0, 1.0)) = 0.5

     _Glossiness("Smoothness", Range(0.0, 1.0)) = 0.5
     _GlossMapScale("Smoothness Factor", Range(0.0, 1.0)) = 1.0
     [Enum(Specular Alpha,0,Albedo Alpha,1)] _SmoothnessTextureChannel ("Smoothness texture channel", Float) = 0

     _SpecColor("Specular", Color) = (0.2,0.2,0.2)
     _SpecGlossMap("Specular", 2D) = "white" {}
     [ToggleOff] _SpecularHighlights("Specular Highlights", Float) = 1.0
     [ToggleOff] _GlossyReflections("Glossy Reflections", Float) = 1.0

     _BumpScale("Scale", Float) = 1.0
     _BumpMap("Normal Map", 2D) = "bump" {}

     _Parallax ("Height Scale", Range (0.005, 0.08)) = 0.02
     _ParallaxMap ("Height Map", 2D) = "black" {}

     _OcclusionStrength("Strength", Range(0.0, 1.0)) = 1.0
     _OcclusionMap("Occlusion", 2D) = "white" {}

     _EmissionColor("Color", Color) = (0,0,0)
     _EmissionMap("Emission", 2D) = "white" {}
     
     _DetailMask("Detail Mask", 2D) = "white" {}

     _DetailAlbedoMap("Detail Albedo x2", 2D) = "grey" {}
     _DetailNormalMapScale("Scale", Float) = 1.0
     _DetailNormalMap("Normal Map", 2D) = "bump" {}

     [Enum(UV0,0,UV1,1)] _UVSec ("UV Set for secondary textures", Float) = 0


     // Blending state
     [HideInInspector] _Mode ("__mode", Float) = 0.0
     [HideInInspector] _SrcBlend ("__src", Float) = 1.0
     [HideInInspector] _DstBlend ("__dst", Float) = 0.0
     [HideInInspector] _ZWrite ("__zw", Float) = 1.0
 }
