With PO you can really use it as much as you want with reasonable settings & play style.
You said you're using PO so I wonder if you're flagged. If so wait the SB out, play legit a few days, do ESP only a few days, then follow this...
Recommended settings if you use AB (ESP only is better):
FOV 4
Time to Target 800
Smoothness 18
Stickiness 1
Target Bone Random
HS % 0
Recommended playstyle:

Many aimbots will inherently cause SB no matter what you do after the server side changes, but not Phantom Overlay.
