First thing first, you do realize in less than two months, Windows 7 will be considered Legacy OS and not supported by Microsoft and probably AMD after January 20, 2020. That means no more Windows 7 Windows Updates and eventually no more Windows 7 Driver updates.
Okay, Here is ASRock own support page showing how to install Windows 7 on the newer type motherboards: ASRock---Installing Windows 7 on Intel 100 / 200 / SoC and AMD AM4 series Platforms
According to the link I posted, if you are using an Optical Driver WITH a PS/2 Keyboard/Mouse you should have no issues installing Windows 7.
But you must have a PS/2 Keyboard/Mouse. If you don't have a green USB/PS/2 Adapter you will need to purchase one.
New hardware is only WHQL for Windows 10 x64, you can still use Windows 7 to upgrade to Windows 10 so modernize and get a fresh and somewhat more secure OS
