Post a picture of the face of the control valve or, describe it, or search for softeners and find one that has the same brand/model of control valve and find out the brand/model name.
Usually there is a way to change the time of regeneration but not always and you have to lie about what time it is but, you do not want to be using water when a softener is in regeneration because you get raw water past the softener if you use water then. So maybe insulating the ceiling over the unit or the pipes etc. to make it less noisy is a possibility. Or maybe your water pressure is too high and that causes the noise.
