UPDATE Nov 16 2021: Apple removed the ability to have a bootable system on a USB Thumb Drive or SD card as of Big Sur, you can no longer do so.
Has anyone found a way to create a bootable SD card on M1 Macs?
Following up from this thread:
It seems like it is now possible to create bootable thunderbolt or USB drives for M1 Macs and boot from them. However, I'm failing to be able to install Monterey onto an SD card.
I like using SD cards to make recovery install "disks" so that I can boot from differing version of the operating system quickly/easily. It really helps when I have some old pieces of software that only run on older versions of the OS and for recovery purposes. And also it helps when I work with my growing collection of vintage Macs where their drives break down and I need to do new installs etc.
The new SD card reader is also pretty darn fast, so for a quick recovery drive, SD cards are super convenient. I know you could make such recovery SD cards bootable with the old 2019 MBP and I think Mojave/Catalina. Seems the ability to boot from SD cards went away in Big Sur.
Thanks for any pointers/help!

Well I tried to make a bootable drive from an SD card and it fails and hangs with the same kind of errors were discussed at length in this thread. So seems to still be an issue. The OS installs on the SD card, but seems like nothing you do will select the drive to be bootable on the new M1 Macs.
M1 Macs, boot from external drive possible?
This thread is over six months old which is a long time in Apple Silicon world. Current Answers: 1) No. In the early days of M1 TB3 3xternals were more successful than USB but USB worked as well. 2) No. I have M1 MBA, with no USB-A ports and have made bootable externals 3) Not necessary IME My...
