Main point is that the nacelle chines result in stall speed reduction. I would be extremely surprised to see any MMEL/AMM permission for an asymmetric absence of chines.
From consideration of the certification effect on performance data and OEM workload to cover the delta, I would be surprised to see any MMEL permission for symmetric absence.
Different matter for the "usual" rows of small VGs - there may well be permissions for some to be missing.
