How to use btrfs raid for data storage

Hi, I am new here. I’ve installed Qubes 4.2.0-rc5 on one of my nvme disk. And the partitions are made automatically by the installer. However there are still four nvme disks unused. I would like to use them as btrfs raid0 to accelerate video editing. I’ve tried to attach it to debian-12-xfce. But there is no response in the file manager. Please help show the right way. Thanks :pray:

Maybe I just need to reinstall the system on btrfs raid0. Hope that would work. :v:
