Boot in different OS with different button

I now have a dual-boot system on my Sony Vaio laptop.

I have this "assist" button next to my power button, it would boot up in an different environment than Windows 10. I now have Linux and Remix OS on it so it doesn't work anymore.

Is it possible in one way or another to immediately go to the other OS when I press the button? It now just boots it normally, I'd like to make use of it.
