I have HP Z4G4 workstation and I need to setup for Autocad. I have connected 4 Samsung 870 EVO SATA drive (1TB) and RAID 10 setup from BIOS. I have removed pre-built 1 magnetic drive that came with Win 10. I have attached 4 RAM with 16 GB. I have attached Quadro RTX 4000 graphics card. When I am installing OS (Windows 10) via USB installer, it shows me drives. It supposed not to show me drive. According to HP article it was not be shown. In my case it shows me drive. Please guide me about what is the issue.

your not making much sense due to translation to English
the windows 10 installer, will always show all available drives it can be installed to
only custom OEM windows 10 installers or a OS IMAGE reinstall will not do this

A workstation is not a playstation!
If you don't know how to configure a Raid-Array you will never be able to troubleshoot a raid-array!
(ex. EFI-troubleshooting when the machine doesn't boot) Raid 10 starts with striping!
Raid 10 is not (!) a safe backup solution. Raid 10 was developed for datadrives and not for systemdrives
If that machine allows you to boot from a NVME it will be faster, easy to handle and safer. A comlete system recovery takes less than 5 minutes.
Separate systemdrive from datadrive!

to "vh200" .....raid 10 is a RENDUNANT configuration, as such it is part of a safe backup solution
A Raid 1 overlaid with Raid 0 combines the data protection of a raid one data redundancy which is then combined with the speed of a raid zero (stripe) configuration, it is also sometimes also identified as RAID 1 + 0 A raid 10/1+0 can recover from a single drive failure just like a raid 5 configuration

A Raid 10 is fault tolerant to one drive per mirrored pair only.
The redundancy is worthless when the striping is not working properly. If you go with Intels RSTe raid solution you have the risk that the next software update corrupts your raid metadata.
A firmware update on a LSI Controller begins with a warning: Backup your data before you proceed. Why?
I have 4 SAS drives waiting to be recovered from such an faulty update.

Raid 10 is a fault tolerant backup,........... but it requires a carefully thought-out recovery plan.
and as you have personally found out one raid array by itself can still leave you up the creek without a paddle
I id "IT" for a living (and still do consulting) and one of the hardest things was getting businesses to understand that a single raid 10/5 or whatever array by itself is not a safe or proper way to do a backup.
PROPER DATA BACKUP REQUIRES MORE THAN ONE COPY, AND NEVER HAVING THE BACKUP CPOPIES IN THE SAME PHYSICAL AREA. also it's up to the person or IT dept to determine just what constitutes a good backup policy that will meet your needs as not everything requires a backup
