pcie gpu addon

So, the new Hades Canyon NUC is on the way. Should be available in March. The big news is that it has a 24 CU Vega GPU integrated into the package. So, we're looking at GTX 1060 levels of performance combined with nearly a desktop class CPU. Basically it should handle most current games...

So I'm currently designing and building my new rig, a TFF (Tiny Form Factor) build, what I'm interested to know is if it's possible to have a Hot-swappable PCIe connection while using either a single 16x slot or 2 * 16x slots via PCIe Bifurcation, I've never done Bifurcation before on a Mini ITX...
