No, that relates to Link Manager Protocol which is carried out entirely
within the controller and I don't think there is any way for the host to
influence any decisions regarding that..

My suggestion is to use rechargeables. They will likely last longer than
alkalines, and I normally have spares already charged (use AA for bicycle
lights) so it never really bothered me to have a flat..
