Liquid Glass:
There are at least two settings you can change to reduce the liquid glass effects:
Settings ≥ Accessibility > Display & Text Size > Reduce Transparency > ON
Settings > Accessibility > Motion > Reduce Motion > ON
If you have updated to at least iOS 26.1 (not to be confused with 26.0.1)
there is additional relief available, but it is not obvious:
Settings > Display & Brightness > Liquid Glass.
Here, you'll find two options: Clear and Tinted.
'Tinted' further reduces the translucency of the glass effect, making it not very glass-like any more.
