Razer Core X Chroma with Razer Blade Advanced 2019, "A GPU switch ????"

Hello I add and connected to my Razer Blade 2019 Advanced the Razer Core X Chroma, So now I have two GPU in my system...one is the 2070 max q and in the Core x an invidia 1080ti Is there a way to choose a program and mostly games to run on this or this ? for now the only way I can choose is by directly connect a DP cable when I want to use the 2070max q to the Blade or When I want to use the 1080ti a DP cable to it... In both cases I work with external Display. (In the case of using the Intel GPU or the invidia Windows 10 allows to choose....same old "Run With Power Saver" or "Run With High Performance") So :) my question is how to choose between two dedicated GPUs in one system? Thanks... Best,
