Install Centos 7 for PowerEdge R650

Hi,

I want to install CentOS 7.6 in R650. I checked that when I logged on iDRAC, it showed 2 physical disks. But when I boot iso to install CentOS, I cannot see any disks. I tried to run with RAID or non-RAID for 2 disks, it didn't work.

I read that OS supported by R650 is not CentOS.

is there any way to install?
