Comment:
I tried it on my system as well. I used fwupdmgr in the past to update a Logitech unifying receiver and it also detects the two SSDs in the system. Efivars is now mounted manually:

```
# mount | grep efivars
efivarfs on /sys/firmware/efi/efivars type efivarfs (rw,relatime)
```

But still I get:

```
├─System Firmware:
│     Device ID:           1d70a31dd3ff0941761550a38436fc990c6c3ff0

│                          • Cryptographic hash verification is available
```

So either something else is required or the firmware cannot be updated via fwupdmgr. In that case the error message would be misleading.

The update command shows me:

```
# fwupdmgr update
No upgrades for Unifying Receiver: current version is RQR12.10_B0032: RQR12.10_B0032=same, RQR12.08_B0030=older, RQR12.07_B0029=older
```

So it only considers the Unifying receiver but not the other three devices. This could be because though they could theoretically be updated via fwupdmgr, there's no firmware for these devices on the server. The get-releases command shows that there are no releases for either of the SSDs and that UEFI is not updateable.
