    • The bands shown in Fig. are illustrative of particular SQS realizations for each x. However, for each SQS-generated configuration we have calculated its band structure, and they are all similar, as shown in the Supplemental Material (Ref.). This collection of SQS band structures generates an energy dispersion for each k point (Ref.). The error bars in Fig. were obtained from this dispersion at the K point.

    • We have also performed calculations for 3n×3n supercells (6×6), where intervalley scattering becomes significant (Ref.). None of our conclusions have changed. This is in agreement with the findings of (Ref.), where the authors show that disorder tends to weaken the effects of intervalley scattering whereas the effects of SOC are not affected.
