Cannot Enable VRCLV and GPU Instancing Together

[Enverex]

As per the title. Doing so causes the shader (metaphira/TableSurface_VRCLV) compilation to fail and go pink.

Shader error in 'metaphira/TableSurface_VRCLV': array reference cannot be used as an l-value; not natively addressable at line 86 (on d3d11)

With the specific shader code section being (line 86 is the one that starts "unity_SHAr")...

      void LightingStandardVRCLV_GI(SurfaceOutputStandard s, UnityGIInput data, inout UnityGI gi)
      {
         #if defined(INTEGRATE_VRCLV)
            float3 L0, L1r, L1g, L1b;
            LightVolumeSH(data.worldPos, L0, L1r, L1g, L1b);
            unity_SHAr = float4(L1r, L0.r);
            unity_SHAg = float4(L1g, L0.g);
            unity_SHAb = float4(L1b, L0.b);
         #endif
         LightingStandard_GI(s, data, gi);
      }

I'm not aware of any other shaders having this limitation but I don't know enough about shaders in general to resolve it myself.
