Need help with turning off polling mode and power management again

The motherboard of my XPS 15 7590 has been replaced because the thunderbolt port had issues, and caused the package power to not drop to 0.3-0.8 watts doing nothing in catalina, now It seems the same issue has not gone away despite the thunderbolt port not being the problem, is there a way to disable polling mode and fix the power managment issues again? I really need answers and would appreciate it.
