How to install Qubes - btrfs on nvme RAID0?

I want to try maximum performance, etc filesystem for pool - btrfs/xfs
and mdadm raid0 on two nvme hard drives.
Are there any anaconda cli installation experts here?
Can you help me how to install Qubes on mdadm raid0 correctly?

sudo mdadm --zero-superblock /dev/nvme0n1
sudo mdadm --zero-superblock /dev/nvme1n1
sudo dd if=/dev/zero of=/dev/nvme0n1 bs=1M count=1000
sudo dd if=/dev/zero of=/dev/nvme1n1 bs=1M count=1000
sudo mdadm --create --verbose --level=0 --raid-devices=2 /dev/md0 /dev/nvme0n1

How to correctly done next steps?
Official docs is outdated :frowning:

  1. crypt disk
  2. open and mount crypted disk
  3. create swap, boot, efi, etc configure what you need.
  4. mkfs.btrfs -L qubes_dom0 -d raid0 /dev/mapper/a /dev/mapper/b
  5. back to blivet gui and create btrfs subvolume root there.

then proceed installation.
