In this note, we study $1/4$- and $1/2$-BPS co-dimension two superconformaldefects in the $6d$ $\mathcal{N}=(2,0)$ $A_{N-1}$ SCFT at large $N$ using theirholographic descriptions as solutions of $11d$ supergravity. In this regime, weare able to compute the defect contribution to the sphere entanglement entropyand the change in the stress-energy tensor one-point function due to thepresence of the defect using holography. From these quantities, we are thenable to unambiguously compute the values for two of the twenty-nine total Weylanomaly coefficients that characterize $4d$ conformal defects in six and higherdimensions. We are able to demonstrate the consistency of the supergravitydescription of the defect theories with the average null energy condition onthe field theory side. For each class of defects that we consider, we also showthat the A-type Weyl anomaly coefficient is non-negative.
