No. A lot of Forum Members just rest the lid on top of the FV or cover it with a bit of Cling Film,
I suggest you just clamp the lid down and forget about it for at least another week.
By the time the bubbles get down to one every hour (i.e. fermentation has slowed down a lot but it's still happening) you will be getting fed up of looking for it - and possibly miss it as well.
Be patient!
