No. When they are in their first month of drying if you seal them up you will have condensation overnight, if not sooner. It takes a little fiddling to arrive at the right ventilation but it doesn't take much to keep it dry inside the bag. Even then, drying it in the bag may not be good in the long run, time will tell. A rotten stave is no good but neither is one that is split from stem to stern. I have had OS that was almost a year drying and we had a cold snap and very low humidity, it split about two feet overnight.
I my shop I have no issues with Yew. It will dry reasonably well in six months, no sealing at all. Longer is better of course
