630UHD graphics with Nvidia !!

I have a h370 gaming 3 Mobo , I5 8400 and gtx 960
I have Catalina working and intel graphics too
the problem that I have to connect the HDMI cable to the Mobo when booting Catalina
and connect it to the Gtx 960 when I boot to windows
is there a way around that
can I boot Catalina with HDMI cable connected to the gtx ?
note: I have to change the display output in bios from pci 01 to Igfx to be enable to boot Catalina without crashing

thank you
