Add disguise self status without changing appearance? (script extender)

How to add the status or passive that come with the DISGUISE_SELF stack id using the console command with the script extender?
I just want the condition but without having to change my appearance.

(I like my TAV's look, and the condition is for wildshape purpose cause some features work in wildshape only if disguise-self is used before transforming).

I tried a bunch of thing using Norbyte search engine but none seems to work for me :/
