India needs to bomb Chinese bunkers using missiles. It's a question of political will, not capabilities. India has all the weapons, including sub-kiloton tactical nukes. China has already broken all previous agreements, so all future agreements are meaningless. China has already come 50 km or closer to Leh on several locations. I would say use bunker buster missile warheads, and if that doesn't work, use subkiloton tactical nukes in Galwan and elsewhere. India is well within its right to do so, and there is plenty of historical documentation to prove that Chinese soldiers are well within Indian side of LAC. Actually the biggest mistake India made was waiting as Chinese got more equipment to build hardened bunkers, and put artillery and anti-aircraft weaponry on Indian side. Indian soldiers should've attacked them well before they dug themselves in. Also, no-first-use is not relevent here in terms of tactical nukes. Imagine if roles were reversed and Indian soldiers were dug-in within 50 km of Lhasa. China would not let no-first-use deter it from using tactical nukes, arguing that it's well within its right to use it as the area belongs to China. If India uses its full military might without hesitation, or falling for Chinese tricks/talks, India will prevail. Start targeting Chinese bunkers, artillery, missiles, SAMs, bridges, dams, airfields to show that invading India has a cost. If India keeps hesitating, it will keep losing territory year after year until the Chinese take Ladakh, Arunachal, Nepal, Bhutan, disputed Kashmiri regions, parts of Uttarakhand, areas south of Doklam, Assam and on and on.
