Safe things to do with Cheat Engine?

So i haven't been playing GTA 5 for 7 months and would like to get back into it.

I used to cheat with cheat engine and these simple things worked:

Changing my XP/level in a mission. Is that patched or does it still work, Would i get banned instantly or should i be fine if i only do like 20 levels max?

Removing the cops/stars with Cheat Engine. Would i get banned removing/editing my police star count?

You can use multipliers for the rp, and yes you can edit your wanted level, (if you make a loop that changes your wanted level and then resets it yo ucan create a rp generator)
