No, it is what Microsoft wants. They made the rule.
You can complain to Microsoft, for what it is worth.
If you have a desktop, you can get an add-on graphics card.
If you have a laptop with usb-c, you can get an eGPU.
However, you are still unsupported unless you use Windows 10. Upgrading to Windows 10 is the easiest answer, and it will not hurt you one bit.
