When this flag is set, Unity culls shadow casters as part of the culling operation.
Default value: set, if your project uses the Scriptable Render Pipeline.
If your project uses the Built-in Render Pipeline, this value is unset if QualitySettings.shadows is set to ShadowQuality.Disable; otherwise, it is set. Note that changing this value has no effect in the Built-in Render Pipeline.
