JavaScript for completely locking pdf after digitally signing

I currently use both Abobe Acrobat XI and Livecycle Designer ES4.

When i want to add the option to completely lock down a document after digitally signing (inc disabling of the 'clear signature' option) i execute javascript within the properties of the digital signature which works fine no problem.

Im lead to believe that Livecycle will remove any scripting from a pdf created within acrobat as it uses its own flavour so to speak.

My question is, does anybody know what the Livecycle equivalent is to have the option of locking after signing (as image) and disable the 'clear signature' feature post signing?

Any feedbcak is appreciated.
