How can i add transparency to this shader?

Hello,

I have this shader that does not support alpha map. How can I modify it so I can adjust the alpha channel so as to be transparent (not cutout)?

Thanks!

 Shader "Custom/WaterDistortion" {
     Properties {
         _MainTex ("Main texture", 2D) = "white" {}
         _NoiseTex ("Noise texture", 2D) = "grey" {}
  
         _Mitigation ("Distortion mitigation", Range(1, 30)) = 1
         _SpeedX("Speed along X", Range(0, 5)) = 1
         _SpeedY("Speed along Y", Range(0, 5)) = 1
     }
  
     SubShader {
         Tags { "RenderType"="opaque" }
  
         Pass {
             CGPROGRAM
             #pragma vertex vert
             #pragma fragment frag
             #include "UnityCG.cginc"
  
             sampler2D _MainTex;
             sampler2D _NoiseTex;
             float _SpeedX;
             float _SpeedY;
             float _Mitigation;
  
             struct v2f {
                 half4 pos : SV_POSITION;
                 half2 uv : TEXCOORD0;
             };
  
             fixed4 _MainTex_ST;
  
             v2f vert(appdata_base v) {
                 v2f o;
                 o.pos = mul(UNITY_MATRIX_MVP, v.vertex);
                 o.uv = TRANSFORM_TEX(v.texcoord, _MainTex);
                 return o;
             }
  
             half4 frag(v2f i) : COLOR {
                 half2 uv = i.uv;
                 half noiseVal = tex2D(_NoiseTex, uv).r;
                 uv.x = uv.x + noiseVal * sin(_Time.y * _SpeedX) / _Mitigation;
                 uv.y = uv.y + noiseVal * sin(_Time.y * _SpeedY) / _Mitigation;
                 return tex2D(_MainTex, uv);
             }
  
             ENDCG
         }
     }
     FallBack "Diffuse"
 }
