Just being honest, this will have a dead GPU afterwards, so you will have to bypass it...

"smc_reset_l is 0.6v"
You must solve this first.
Check diode mode to ground on that line.
Also post U5010 voltages.
Remove R7000 and check again SMC_RESET_L.
Be sure R5000 is OK.

When finally GPU dies, you can disable it in BIOS with Medusa.
