Yes, you can change it. From memory only (I might forget something here). Remove the stock from the action. Remove the retaing clip that holds the safety button. Remove the large "L" shaped bar under the safety button and the safety rod that goes to the toplever cam. Flip the rod around so the collar on the rod no longer engages the "L" shaped bar, reassemble all parts. It's the collar on the rod that pushes the safety back to the "safe" position, if the rod is flipped around, the collar no longer engages the "L" bar and doesn't push the safety on.
I think my picture shows it after I've flipped the rod around. Note that the collar is quite a way from the "L" bar and when the toplever cam pushes it back, it would not travel enough to set the safety. (disregard that arrow as this pic was for some other topic long ago)
