    Unfortunately i have not found a way to do this without changing URPs code. But if you are fine with that, the most minimal change you can do is in the
    "Packages/com.unity.render-pipelines.universal/ShaderLibrary/AmbientOcclusion.hlsl" shader. The method
    GetScreenSpaceAmbientOcclusion(float2 normalizedScreenSpaceUV)
    uses an #ifdef to return the ambient occlusion factor. You could define a shader keyword in your material and add it to the #ifdef.
