Console output going to vga port instead of nvidia card

Latest response

Hope someone can help.

I have a RHEL 7.3 system with an nvidia quadro card using the 375.XX drivers. The motherboard also has an internal VGA device (ASPEED Graphics Family).

I cannot disable the VGA port in bios, only set priority for offboard Vs Onboard (Supermicro bios). I can get graphics to work, but when I switch to Virtual Terminals of non-graphical modes( multi-user.target), the consoles are only output on the vga port.

I have tried various combinations of kernel options to try and force the output to the nvidia board with no success. (rd.driver.blacklist=ast rd.driver.blacklist=nouveau vga=normal video=vesa:off)

Any suggestions on how to stop the system from seeing the vga board at all?
