How to set bleed values via scripting

I have over 200 eps files which have the bleed value set to 5mm. I need to set it to 0mm (I.e. so there is no bleed)

Is there a way to do this via scripting?

I have had a good look on the internet, but all the solutions seem to be for reading bleed values. It's not clear how you can adapt the code to set bleed values.

If its not possible, is there any other way of batch setting bleed values?

Thanks in advance for any help that can be offered!
