TET - the flare increases the Nr - the pull, check or click on the collective does the opposite.
If you check whilst flaring, the flare effect may well overcome the extra drag from the check but raising the lever does not increase Nr no matter how quickly you do it.
It is feasible, with an aft C of G, that raising the lever will bring the nose up slightly effectively giving an increase in the flare effect but it is still flare effect that is raising the Nr.
