You can add a custom key (say Users) to the .inf file created by the /SAVEINF.

Then in the installer, lookup the /LOADINF command-line argument and read the key and act accordingly:

procedure InitializeWizard();
var
  InfFile: string;
  I: Integer;
  UsersDefault: Integer;
begin
  ...

  InfFile := ExpandConstant('{param:LOADINF}');

  UsersDefault := 0;

  if InfFile <> '' then
  begin
    Log(Format('Reading INF file %s', [InfFile]));
    UsersDefault :=
      GetIniInt('Setup', 'Users', UsersDefault, 0, 0, ExpandFileName(InfFile));
    Log(Format('Read default "Users" selection %d', [UsersDefault]));
  end
    else
  begin
    Log('No INF file');
  end;

  SelectUsersPage.Values[UsersDefault] := True;
end;
