No, it doesn't need to be quoted. These values work correctly as raw `true`/`false` without quotes.

Specifically, I've verified that `true` outputs the necessary methods, while they are not present with `false` (no quotes on either):

`SSDT1.dsl`
```
    Scope (_SB)
    {
        Method (DDEF, 0, Serialized)
        {
            Debug = "DPTC: Using normal SOC DPTC Settings."
            Name (DEFB, Buffer (0x25)
            {
            ...
            })
            _SB.ALIB
            0x0C
            DEFB
        }
    }

Scope (_SB)
    {
        Method (DTHL, 0, Serialized)
        {
            Debug = "DPTC: Using low/no battery mode SOC DPTC settings."
            Name (THTL, Buffer (0x25)
            {
            ...
            })
            _SB.ALIB
            0x0C
            THTL
        }
    }

```

If it's just for consistency's sake, I can add them, but it doesn't appear to be necessary.
