'nvme0: Admin Cmd(0x7f), I/O Error (sct 0x0 / sc 0x1)'
They allow the host OS to send vendor-specific additional or customized commands to the NVMe controller.
In this case the controller responded with 'invalid opcode' (sc 0x1) which indicates that the controller does not support that specific command received.
The OS itself does not issue these commands; they usually come from other third-party tools that are not part of the OS.
