Black screen appears when installing centos 8 but centos 9 stream can be well installed

[dfc]

I have tryed to install centos 7, centos 8, centos 9.But only centos 9 can be installed.
I have already checked the checksum.Checksum is right.
Now I need to use Centos 8.Is there any way to help me solve this problem？
cpu: Hygon C86.

Does it work if you use the basic graphics option that's under the initial Troubleshooting menu when you first boot?

I've tried, but it doesn't work.Selecting this also causes a blank screen.
I may have found the reason.Linux kernel supports the hygon cpu in 4.20,but linux kernel in Centos 8 is 4.18.
