How to build software raid 1 on ReFS in Windows 2019?

Question

Windows Server

Hello! Q: How do I create a mirrored RAID 1 volume for ReFS on Windows Server 2019?
It is not necessary to read below if the question is clear.
I used to use mirroring on dynamic disks in ms windows for my tasks, now I use ZFS on proxmox, of course, in terms of functionality, these are very different things, but for me one of the critical advantages is that when a power failure occurs, zfs does not immediately synchronize all disks like this occurs in case of mirroring on dynamic disks.
Not so long ago I learned about ReFS, today I tried to install ms server 2019 on a test machine, it turned out that ReFS does not support booting, I made a system partition with mirroring on dynamic disks with NTFS, 50GB in size to synchronize data faster. I created a second partition, formatted it in ReFS and did not understand how to add a mirror volume to it. I read the manual from MS, a lot of information, for a seemingly simple task. I came to the conclusion that ReFS is used only for virtual machines, but still I hope that someone here will tell you if it is possible to do this and in what direction to move.

To make a software raid 1 (mirror) on Windows server 2019, you need to take into account the requirements
1. ReFS does not support loading (does not support on 10/31/2019, maybe they will add it later).
2. The disk must be clean before adding it to the raid (there must not be more than one partition, otherwise you will not see it
in the physical disks block in the screenshot marked 3)
3. If I understand correctly, ReFS plays the main role here, i.e. in fact, the technology that MS called virtualization of disk space (storage spaces) is used and you can also use ntfs. Again, if I understand correctly, this is an analogue of linux LVM. If you are familiar with LVM for ease of understanding in storage spaces the terms physical volume = physical disks (3 in the screenshot), logical volume = virtual disks (4 in the screenshot), volume group = storage pools (2 in the screenshot).
To assemble a software raid, you need to go to the server manager - 1 file services and storage services - 2 create a storage pool in which you can use disks from the list 3 - 4 create virtual disks based on this pool, the "storage structure" mirror is already selected there.
