To optimize network performance for an object that does not move or rotate after being spawned, which property of the NetworkTransform component should be modified?

To optimize network performance for an object that does not move or rotate after being spawned, modifying the Network Send Rate to 0 is the most effective choice.

When an object's state is static — meaning it does not change position or rotation — there is no need to continuously send updates over the network regarding its state. Setting the Network Send Rate to 0 effectively tells the network not to send any updates for that particular object. This reduces unnecessary data traffic, which can enhance overall network performance and reduce bandwidth usage, particularly in environments where many static objects might be present.

The other options do not provide the same level of optimization for a static object. For instance, enabling interpolation would be useful for smoothly transitioning moving objects, but it would add overhead that is unnecessary for a static object. Similarly, setting a sync interval to 1 second would still mean that the object would send occasional updates, which is pointless if the object does not change. Auto-enabling on spawn relates more to whether the object starts sending updates immediately, but in this case, avoiding sending any updates at all is preferable.
