So at this very begining of the day I picked up an oldie machine Dell T620 and decided to want JBOD for ZFS, better IOPS and easier management.
So it turns out that is very possible by cross-flashing the DELL PERC H710 firmware to LSI IT firmware.
Why is this so important? Because ZFS wants HBA, JBOD.
IT mode stands for "initiator target". It presents each drive individually to the host.
HBA is the term Passthru simply implies a RAID card that is not performing any RAID activity on a drive and is often also known as HBA mode. In Passthru mode drives are presented by the RAID card for discovery just as if it was an HBA, and IO to those drives bypasses most RAID functionality.
I found a very very good article how to do that at https://fohdeesha.com/docs/perc.html
therefore many thanks for those made this possible.
So here is what I experienced so far with DELL PERC H710 B0 ...
Following the article before all I had to disable every virtualisation technology, such as
[Processor Settings > Virtualization Technology]
[Integrated Devices > SR-IOV Global Enable]
[Integrated Devices > I/OAT DMA Engine] in the BIOS and I must ensure that only one RAID component installed onto motherboard.
The article suggest to remove the battery, that I have already removed years ago.. so skipped this part.
There is .ZIP file which contains two ISO images, FreeDOS and Linux prebuilt.

The firmwares can be restored by issuing command from FreeDOS:
