when hidding an object it should not be calculated in the time it takes to render

[digital_technologies]

Usually when I import an animated heavy vrscene, like an animated tree, when hit render it usually takes some time to refresh every frame, which adds a lot in the overall rendering time of the animation.
if I would delete this vrscene or geometry then the refreshing of each frame goes back to very fast.
I would expect the same to happen if I would hide the vrscene or geometry , but this is not the case,
The refreshing of each frames still takes long even if heavy geometry is hidden
