PVE reinstallation without wiping local storage

[mdo]

We have a running PVE installation with separated local storage on 2x SSD (Hardware RAID1) for the OS installation and a second hardware RAID array (RAID 10) for all VM storage. Both RAID on the same controller.
This was installed about a year ago by a team member in a non-standard way (I believe Debian first, then PVE 5.2 on top).
A recent attempt to upgrade the OS to the latest version 5.4 failed and we must have taken wrong, manual steps so that we are in a position wanting to re-install the OS freshly (and then restore its former configuration, VMs, etc.)
During a fresh, standard PVE install onto the SSD RAID, can we be sure that the second RAID array with the VM storage will *not* be touched (formatted) in any way?
Thanks for any help.

I would recommend you to pull out these drives, then you are really secure.

But normally, if you don't select them, they will not touch.

Thank you for your help. We were careful with our selection and it all worked out as planned. The "Data RAID" was untouched in the process as expected.
