This is the Blizzard nameplate debuff filter:
https://github.com/tomrus88/Blizzard...lates.lua#L134
This is the debuff filter in oUF_SimpleConfig (it is the same):
https://github.com/zorker/rothui/blo...eplate.lua#L78
You can use a custom filter in oUF to filter out specific icons.
This is how oUF will call you
https://github.com/oUF-wow/oUF/blob/.../aura.lua#L195
This is how you define the function in your layout:
https://github.com/p3lim-wow/oUF_P3l...P3lim.lua#L382
https://github.com/p3lim-wow/oUF_P3l...P3lim.lua#L218
Blizzard has this function here for aura filtering:
https://github.com/tomrus88/Blizzard...lates.lua#L435
Basically all you need to do is copy-cat that function and make it your nameplate custom filter.

local function CustomNameplateFilter(...)
  local _, _, _, name, _, _, _, _, _, _, caster, _, nameplateShowPersonal, _, _, _, _, nameplateShowAll = ...
  return nameplateShowAll or (nameplateShowPersonal and (caster == "player" or caster == "pet" or caster == "vehicle"))
end
self.Debuffs.CustomFilter = CustomNameplateFilter

Btw what was "shouldConsolidate" is now "nameplateShowPersonal". Maybe that should be changed in oUF/elements/aura.lua.
