Bootable RAID 0

[_Dave_]

Could anyone point me in the direction of installing MacOS on a bootable RAID array, preferably Big Sur or Monterey?
I have a mid 2012 MacBook Pro (non-retina). I have two internal SSDs and have installed MacOS Monterey (no RAID) using Open Core.

I understand that MacOS may have officially stopped supporting bootable RAID arrays with High Sierra (10.13). But I also have an unsupported version of MacOS installed currently. I have also seen posts of people successfully booting Catalina off of a RAID array.

My question is: has anyone seen info regarding bootable RAID arrays for Big Sur or Monterey? Have you seen any for Catalina?

This guide help me install Catalina in my RAID-0 dual SSD over Thunderbolt. Works well so far. Hope there are guide/ workaround for Big Sur and newer. Tried all the patcher and OCLP. Doesn’t work.
