At this stage I'd wait until it's dry but monitor the smell closely -
the CO2 won't help much if you get H2S. You can also stir the lees once
a week or so, it will also help the yeast . I do this pretty regularly
without H2S issues (knock on wood) if the ferment was clean. I used to
rack off the gross lees early before but got a stuck Merlot that way in
a very similar situation you are in.

These days I usually wait until complete dryness before pressing.
