Without plugin, no.
It's a group setting:
/* Can the member report content? */
if ( $member->group['g_can_report'] != '1' AND !\in_array( \get_class( $this ), explode( ',', $member->group['g_can_report'] ) ) )
{
return 'no_module_permission';
}
Added in new version. It's uploaded and waiting on approval.
As said before, use my other mod instead.
I doubt it will help. Rather overload support panel. I may do that as custom work for you, pm me for details.
