Well, I still haven't found an answer, but this is what I've run into when searching through WWW

Linux*
Beginning with Linux* kernel version 2.6.18*, the dmraid* utility 1.0.0-rc15 supports RAID 0, RAID 1, and RAID 10.
Beginning with Linux kernel version 2.6.27*, the mdadm* utility 3.0 supports RAID 0, RAID 1, RAID 10, and RAID 5.
The kernel provides the RAID level support. The utilities support the Intel® Matrix Storage Manager metadata format.
To use the RAID features in dmraid and mdadm, set up the RAID volume using the Intel Matrix Storage Manager option ROM. To enter the option ROM user interface, click CTRL+I when prompted during boot.
Instructions on how to use the RAID features in dmraid and mdadm are included with Linux. This information is provided as a courtesy by Intel. Contact your Linux vendor for additional questions and support.
Still I'm not sure what I'm doing wrong. Is it possible that distros like Kubuntu or Manjaro just don't have RST option compiled in their kernels?
Looks like posts on the forum at msi.com have similar reports. Either you convince msi to fix their bios, or you switch to AHCI mode, and either reinstall Win 10 on bare metal again (it might be able to do intel raid without BIOS support, just like Linux) or install Win 10 in a VM.

Why do you think MSI BIOS is broken? Windows 10 seems to be working flawlessly on my machine. The only problem is the visibility of NVMe SSD disks in RST mode under Linux.
Why? Here’s my reasoning: Windows 10 on my machine in AHCI mode can use Intel RST. There doesn’t seem to be a need to have a “RST” option in the BIOS. So whatever MSI is doing to make RST not work under Linux doesn’t seem to be necessary for Windows, at least on my HP machine. If I were you, I’d post this specific problem on msi.com or even call them, and get them to address it.
If you have Intel RST RAID technology in you laptop, could you please check if Kubuntu or any other Linux distro can see the NVMe SDD disks configured in RAID array and with RST option turned ON?
P.S. Open SUSE Tumbleweed doesn't detect my RST RAID array too...
They're just changing the hardware ID when you go from AHCI mode to RAID mode. That's it. IF you do enough searching, you'll even find a few people who found the hardware ID that MSI sets, edited the files so it associates the correct drivers again, and it works just fine again. It's just they're using a Hardware ID that isn't normally used.

Any idea how to check those hardware IDs and what to do in order to make Kubuntu (or any other Linux distro) installer see those drives?
Well, running live lspci should allow you to see the hardware ID's, htat's the easy part. As far as editing whichever files are needed so that the kernel knows which drivers to associate, that I don't know. I did do an install on one of these devices, but the user didn't need to keep Windows, so I just switched it ot AHCI mode, installed and continued on. Since it was a laptop (single drive), there is no actual difference between AHCI and RAID modes.
