The ability to enable QNAP SSD Antiwear Leveling (QSAL) on an existing storage pool depends on the QuTS hero version running on your NAS:

Firmware Version	Can I Enable QSAL on an Existing Storage Pool?
QuTS hero h4.5.2–h5.0.1	No. QSAL can only be enabled when creating a new storage pool and cannot be disabled later.
QuTS hero h5.1.0 or later	Yes. You can enable or disable QSAL on a storage pool at any time.

To enable or disable QSAL on an existing storage pool in QuTS hero h5.1.0 or later, follow these steps:

Open Storage & Snapshots.
Go to Storage > Storage/Snapshots.
Select a storage pool.
Note
To enable QSAL on a storage pool, the pool must contain a RAID group that meets the following requirements:
- The RAID group must be one of the following RAID types: RAID 5, 6, 50, 60, TP.
- The RAID group must contain at least two SSDs that can provide estimated life remaining.
- At least one SSD in the RAID group must have over 3% estimated life remaining.
Click Manage.
The storage pool management window opens.
Click QSAL.
This tab only appears if the storage pool contains a RAID group that meets the requirements for QSAL.
Optional: Select a different RAID group.
Click the toggle button to enable or disable QSAL.
Click Close.
