Does GPU instancing loads related materials or models into memory even if theyre not in the scene?

so if I enable Gpu instancing, does it take all materials and models into memory? even if theyre not in the scene?

im asking bcuz theres many materials and models that i will load later during the game into the memory. about 99% of my materials and models, which result in hundreds of megabytes will be loaded after some time in game, not in first location

thats why i need to know if GPU instancing doesnt load them into memory at the start
