Thank you but this card is not seamless. Here is a note listed with the card:
Note: With this Metal-compatible graphics card installed, you will not be able to see the Apple logo at boot, nor can you access boot options. Once your system has fully booted, the graphics card will function normally. For more details (including workarounds), see the Rocket Yard article on How to Get Ready for macOS Mojave. There are no driver(s) or Catalyst/Adrenalin support on macOS.
Right it’s not seamless but it will work. Personally I don’t care if I see the boot screen. I believe Any card you use will cause this to happen.
