Turning off pre-load instrument while in Mediabay

I have looked everywhere in the manuals for Cubase how to turn off pre-load of instruments while in mediabay or presetmanagers.
It’s tediuos to have big drum libraries start to load 4Gb of data everytime you rest on a presetname.

Especially tedious while using the CMC-AI as you have to turn the knob back and forth to prevent this to happen.

Anybody that knows where to look?
