Alterations from bulk to cut.

I am currently bulking ahead of an upcoming cutting phase.

Currently I do about 6 exercises each workout 3 times a week, mostly 4x12 range, reaching failure.

When I start cutting I want to add some cardio but also dont want to add to time in the gym, as I already spend 1,40 - 2 hours in the gym.

As the cutting phase is about maintaing muscle and not necessarily growing, can I scale back to 2 sets pr exercise if I up the weight to still reach failure?
