As the approach is designed for a temperature of -25°C including the DA for that temperature (any higher temperature simply increases the safety buffer) i would fly the approach in managed/managed with the published uncorrected DA.

If the temperature is lower than -25°C it has to be flown either in FPA/TRK or FPA/NAV with the temperature corrected LNAV mininum.

That is in line with our OM-A guidance:
No corrections are needed for reported temperatures above -15°C or if the aerodrome temperature is at or above the minimum published temperature for the procedure being flown;
@de facto: the correction-tables in both airbus and boeing documentations are exactly the same, at least on our fleets. Well, the minor difference is that the boeing documentation has the tables additionally in meters and airbus has a few more heights up to 5000ft whereas the boeing table ends at 3000ft.
