Both cards support CUDA so if you install the CUDA SDK as long as the card is detected (graphic drivers or not) the CUDA SDK should enable the card to be used by hashcat.
Otherwise, I think the problem is that the RTX card will have newer Nvidia drivers than the 1080TI can support. So, I'd suspect a proper sequence of installation may be required. So I would install the RTX alone in the PC and confirm its working appropriately. Once that has been confirmed, add the 1080TI alone and install the drivers for it. Reboot and add the 2060 back in and should be good to go.
