On the team instructions set defensive line to lower.
Also set duties to cover (1 or 2 defenders not all 3) as these will drop behind the line to clear up through balls whereas a stopper will rush out causing the line to go higher.
Yes, on the player instructions put 'close down less' to the players set as cover and this should counter this while the others pressure the ball.
good luckAlso, how quick are your CBs??
