I muck with the OS and above all the time, and I somehow can’t remember I ever needed to restore my bios. No. Never. Really. But M1 macs need the internal storage to work and be intact to boot even from external media. If the internal ssd on my intel mac or dell xps tablet (the soldered one, yep) dies, I boot from usb3.1 and keep on keeping on. The M1 Mac is a brick after that, except the new mac studio where the ssds are somewhat replaceable.
