Is there any way to completely avoid pd from splitting and scheduling hot regions? Currently, the pd parameter hot-region-cache-hits-threshold is set to 60 minutes, but checking the logs still seems to show hot region scheduling information.

Try changing hot-region-schedule-limit to 0

tiup ctl:v6.0.0 pd config set hot-region-schedule-limit=0

It seems that this still cannot avoid the split of the region. Is there any other way?

A region has split into 4 regions.

Try increasing the Load Base Split threshold and see:

set config tikv split.qps-threshold = increase it;
set config tikv split.byte-threshold = increase it;
