This seems to be still partly broken in v1.3.8 for some combinations and some ordering of parameters. See official Unity Discord, channel #dots my Post

Known Bug? The JobEntityGenerator creates broken DefaultQuery for "EnabledRefRW, ref"

(links to discord is not allowed).

basically:

using Unity.Entities;

struct Comp : IComponentData, IEnableableComponent { int i; }
partial struct TestSystem : ISystem
{
[WithPresent(typeof(Comp))]
partial struct JobWorks : IJobEntity
{ void Execute(ref Comp c, EnabledRefRW<Comp> ec) { } }

[WithPresent(typeof(Comp))]
partial struct JobBroken : IJobEntity
{ void Execute(EnabledRefRW<Comp> ec, ref Comp c) { } }
}
