The Germans didn't finalise their plans for the invasion of the Soviet Union until end of July '40 with an intended start date of May '41, so I doubt they were in a position to 'go east' after Dunkirk.
Not going as planned in May '41 was a mistake on their part, as was grossly underestimating the strength in depth of the Soviet forces, and then Hitler overruling his General's in ordering a large proportion of Army Group Centre's units north and south to assist Army Group's North and South at Lennigrad and Kiev stalling the drive to Moscow until late autumn and too close a proximity to the onset of winter.
