Alternatively, if you can't keep them extended for ground handling:
a) Close everyting up on taxi-in.
b) Refuel.
c) Extend to 1+F.
If you get the warning during the turnaround, remove the bleed source and let it cool down with increased ventilation once the slats are extended.
If you don't get the warning at all, perhaps you can just ignore it because it does not apply to your configuration.
NOTE: avoid urge to fine-tune and go for 1+0 just because it says SLATS. This could turn ugly as the lever and flaps are not in synchronous position
