As we see the disk support Firmware Image Download command (0x1 FW Commit and Download Supported), has 3 Firmware Slots (0x3 Number of Firmware Slots) and 1st Firmware Slot in Read/Write mode(0 Firmware Slot 1 Read/Write) but I don't recommend using it.. Try to use free Firmware Slot, do not overwrite the original firmware.

Lets download firmware to controller SRAM

$ sudo nvme fw-download -f firmware.bin /dev/nvme0

Firmware download success

Write firmware to free Firmware Slot 2 without activation

$ sudo nvme fw-commit -s 2 -a 0 /dev/nvme0

Success committing firmware action:0 slot:2

Activate new firmware

 $ sudo nvme fw-commit -s 2 -a 2 /dev/nvme0

Success committing firmware action:2 slot:2

Reboot and pray )
