Stripes on the inner wall near the holes

Hi guys,
Need some advice. I got my P1S at the beginning of this year. Generally it prints well, but there is one problem that I still can’t solve. I have prepared a test model to show the problem. On the inside wall, there are
stripes around the holes. In my case I need the inner wall to be perfect. I have read a lot of advice on the net, including on this forum, changed the size and shape of the holes, tried 3 different PLA manufacturers (including bambu basic), but these stripes are always there.
I realize that the stripe appears because of physics, different speed of printing layers and temperature, but I can not remove this stripe. The outer wall turns out to be of good quality, but inside there is always a stripe. At first I tried Bambulab Studio, but now I have switched to Orca Slicer.

What I did:

  • I used profiles 0.12, 0.16, 0.20.
  • Used Generic PLA preset
  • Used Bambu PLA Basic presets.
  • Calibrated filaments, changed Flow rate, Pressure advance, Max volumetric speed.
  • Changed nozzle to non-original nozzle
  • Reduced speed
  • Changed cooling
  • Turned on/off Slow down for overhangs, Auto cooling, Don’t slow down outer walls, Inner/Outer/Inner and others.

In the photo - the green filament is Bambu basic. The first photo is quality without holes.

Maybe there is something I missed? Or do I have something wrong with the mechanics of the printer? I don’t believe it’s impossible to get rid of these streaks. The only place where you can hardly see the stripes is if you turn on the Fuzzy skin. I can attach the stl file.
Thanks!
