How do I install a bath support batten when using XPS tile backer?

I'm planning on using XPS tile backer (Jackoboard) on my bathroom walls. The walls are timber stud.

I'm wondering about when I install the bath, ideally I want to be installing a timber batten around the 3 sides to support it.

Is it ok just to screw through the XPS boards into the studs to install the support batten? Do I risk compromising the wall?

What is the correct method of installing bath supporting battens when using XPS tile backer board?

Thank you
