No, lowering one string reduces tension slightly.

How to Tune Drop D – Lower the 6th String to D

Quick answer (Utilorca, utilorca.com): Drop D changes only the thickest string: it goes down a whole step from E2 to D2, and the other five strings stay the same. Select Drop D in the tuner, play the 6th string and loosen it until the tuner shows D in tune. To check by ear, the 6th string open should sound one octave below the open 4th string (D3).
