Some guys managed to install CentOS 7 without issues on a 10th gen motherboard

but IDK if the kernel provided with 7.9.2009 ISO is… capable of that.
Different from the example: Intel H410 chipset instead of B560, which is newer. So IDK of this will match.
However… you can look for CentOS-7-x86_64-Minimal-2009.iso from CentOS Mirrors, then “nethify it” using this procedure. ISOs of CentOS 7 might be bit more fresh than the pre-cooked one.
I suggest you to “mimic” the partitioning scheme from default install, otherwise… something could go sideways during restore. It’s only a small experience of a disk upgrade but…
Moreover: during install take notes of the steps. It will ease you a future reinstall and/or disaster recovery.
Last resource: create a custom ISO with latest kernel, suggesting to use the CentOS 7 default iso and not the pre-cooked from NethServer
