SSD not detected in OS Recovery.
Hi, I have 2015 MacBook Pro with an upgraded SSD, a Samsung 970 Pro M.2 SSD.
I update Mac OS to 11.1 and want to made clean install. Tried to boot in recovery mode, but Disk Utility doesn’t recognize the SSD.
In terminal with command “diskutil list” I see only SD card and recovery 2GB disk and bunch of small partitions about 500kb.
When I boot the system I can see the SSD and system working fine.
Es esta una buena pregunta?

I'm still a bit lost here. Can you take a snapshot of Disk utility expanding the different layers in the left column posting the pics here Agregar imágenes a una pregunta existente. If you can see the boot partitions then you didn't wipe the drive fully.
Also are you using a Big Sur boot drive (2TB external)? Or the OS recovery services off the internet?

Did you solve the problem? I have same problem. When I start up the Mac and us it, it works perfectly fine, but I want to erase and start clean OS and I can't do it because disk utility in recovery mode does not show the ssd so I can not delete it.

@Editor - Yes, that can happen!
You're hitting a known issue because your recovery OS release only works with HFS+ file systems and has no clue about APFS file systems so it can't see it! This gets back to not using recovery!
Instead create a bootable OS installer based on Mojave or newer! Then that version of Disk Utility will see the APFS partitions and you can delete them or reformat it.
FYI - I only use bootable OS installers for each release I've got over a good half dozen which I use and just as many which are tucked away with older versions.
