Short answer - no.
Start reducing the power towards idle at approximately 30', aiming to reach idle at touchdown. Prevent the tendency for the nose to drop with elevator & then flare the aircraft at the appropriate point. Believe it or not, I usually flare immediately after the 10' auto callout is made (if it is working - or purely by visual reference if not), the callout backing up the visual picture.
Some have been taught that the A/C will 'fall out of the sky' if you don't carry power into the flare when using flap 40. It wont as long as you prevent the nose from dropping & then positively flare the aircraft. If you try to do a proper flare without taking the power off it will balloon. To avoid a balloon without taking the power off at the appropriate time, you will end up with a very flat landing (almost a 3 pointer) & also have the possibility of a long landing. I see it all the time.
Good luck with it.
