From the theory dictionary:

• global_nx
  • useless: it's probably the number of points in the xgrid when it's not the standard (default: 0)
  • used only for few theories annotated with "LOW PRECISION NNPDF3.1 NNLO central"
  • available in yadism specifying your own interpolation grid
• EScaleVar
  • probably: ExcludeScaleVariations
  • solved by introducing fact_to_ren_scale_ratio as extra and only parameter in eko
