I assume you think Q1403 is short because it is getting hot? Q1403 will always get hot on short on VCC_Main. Remove Q1403, add voltage to line after Q1403 and find real issue causing the short.

Q1403 connects vbatt to vcc_main. If q1403 getting hot it's because there is a short on vcc_main

pmu doesn't work when vcc_main is short because there is a huge voltage drop...

You don't need to remove Q1403 as long as vbatt is not shorted.
Just jump power to VCC_main and find the hottest cap without heating up Q1403
