not that i have seen.
though if you have two laser blades (same, of course never tried with two different ones) you can fly forever by slashing with one, then the other, and repeating by holding down the firing buttons. the blades use up as much EN as they need to Quick Boost then attack.
In AC4 and ACFA the blades use up minimal EN
