That might be a maintenance issue and not an optimization issue.
Especially since it is a laptop. A little dust could be blocking airflow leading to overheating video card.
Personally I had no overheating problem (card was 40-50 C the entire playtime) although there was a lot more hot air coming out of the case than I thought the graphics would warrant given it has no RTX. If this were summer and the case couldn’t dump the hot air into a cold room I’m sure my temps would have been hotter.
