With the GIANT disclaimer that different riders, in different locals, riding different distances, ways, etc will have different experiences and I always recommend going with with your experience and/or the best local advice...
The new SKF made seals that Fox (and RockShox) use are astoundingly better than the old models in terms both smooth action and resilience and unless they look really dirty inside when you pull the lowers you should be able to get a lower service (clean / fresh oil) out of a set without having to change them.
The average local rider (Shore To Sky) is well served to do a basic service every 50hrs (just clean/fluids) and a full service every 100hrs (seals, bleed damper if it’s a bladder model, air system).
Some riders who do a lot of winter miles will add an extra lower service just to keep everything clean but again no seals as they should last ~100hrs if riding.
YMMV, always follow the manufacturers’ recommendations, etc, etc...
