I would reword this to:

will be untouched"
+- strict-supply-voltage: <1|0> Set/Reset STRICT flag in CONFIG1
This is too less info on the strict bit:
You can perhaps add some more description from data sheet.
The Supply Voltage supervisor has two modes of operation, controlled by
the STRICT bit. With the STRICT bit set to 0, all
enabled rails of the five regulators are monitored for undervoltage only
with relaxed thresholds and
deglitch times. With the STRCT bit set to 1, all enabled rails of the
five regulators are monitored for
undervoltage and overvoltage with tight limits and short deglitch times.
+- under-voltage-limit: Select 2.75, 2.95, 3.25 or 3.35V as UVLO in CONFIG1
Again some more description on uvlo please.
+- under-voltage-hysteresis: Select 200mV or 400mV UVLOHYS in CONFIG2
Even here for hysteresis.
