How to fix Z band and VFA artifacts?

I am curious how to fix the z-band which is persistent across prints. Happens around 26mm. All objects shown in the photos are printed using PETG Anthracite Prusament. Self-assembled Core One, which has been running for a bit less than a year. Not using the printer much, but on bigger objects I noticed the thick z-band. Running latest firmware(6.5.3) and PrusaSlicer (2.9.4).

Another issue are the VFA artifacts, though less of an annoyance than the z-band. The belts are tuned using the built-in stroboscope belt tuner. Though I know this filament makes the vertical artifacts more present due to the shininess.
