Disabling unsupported graphics card

[worldie]

Hello, my Hackintosh is working fine, but I swapped out my 1070Ti to a 2070 for gaming on my windows ssd. And i know that there are no rtx drivers out, so here is my question: can i just disable my graphics card, and only use the dedicated graphics on my cpu? If yes, please tell me how
It isn't just disabling it in the bios, right?

Thank's for the help!
