There is 0 motive for India to fire unprovoked tbh. It suits India to keep Kashmir off the radar and not help the Pakistani army gain popularity in Pakistan. Indian government is talking on it's own terms on issues it wants to with Pakistan, while largely avoiding the Army.
UNMOGIP is a tactical move anyway, as they know that India since 1972 hasn't dealt with UNMOGIP After the Shimla and Karachi agreement's. India has even restricted their activities in India. To quote Wiki -
India and Pakistan disagree on UNMOGIP’s mandate in Kashmir because India argued that the mandate of UNMOGIP has lapsed after Simla agreement because it was specifically established to observe ceasefire according to Karachi Agreement.
So while Pakistan would want them to get involved in Kashmir again, India would want some other organisation to probe.
