I would think that if this is only the second racking, the it's probably not a finished wine and I would not degas at this point. You typically only degas a gassy wine right before bottling, if the gas doesn't dissipate on its own. Once the wine is completely clear, and no longer dropping lees after at least 60 days, then it can be considered "finished" and then bulk aged or prepared for bottling. By then, it should be degassed on its own.
