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.

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 在已经存在的问题里加入图片. 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.
