Will DFU Restore delete all the Partitions in the SSD to Factory Defaults?

I was playing with Asahi Linux installation, and now I have a mess with the disk and partitions, I can't delete the Linux partition to recover the full disk capacity, thanks

DFU Restore erases everything, so yes, all partitions will be gone.

Confirmed. I found out the hard way as I was expecting it to only delete the Volume I was booted from, in a dual boot setup.

Duh! Realised I was thinking about "Delete all content and settings" not DFU when I wrote the above

I have done DFU restore on Mac and it does erase all volumes as @mr_roboto says. So does "Delete all Content and settings" except DFU wipes firmware and Recovery as well of course.

Sorry for the ignorant question:
I've seen the term "DFU" bandied about numerous times.
What does it stand for?

Yes they result in the same thing: the key that the NAND is encrypted with is permanently changed. So it’s technically not erasing anything, it’s just the data becomes unreadable.
