If its permanent, I'd not be too worried about drilling holes and using
small self tapping screws. My roller blind has been up for five years with
no problems. Its a Wilkinson's one.
Of course it goes without saying that you need to make small holes and do
not over tighten the screws. Most of the innards of the blind seems to be
held together with little self tapping screws into plastic, in my one and
nothing has cracked or stripped its threads.
