Query Regarding How to Disable A Feature In Finder On My Mac

Hi, just a quick question that should be easy for someone to help me with. I've only just got my new Mac and I can't remember how to turn off column preview in tables. It's driving me crazy especially in Finder.
When I looked for the post all I found was one that was talking about autoscrolling.
What I 've tried:
VO utility, then go to to navigation but that was suggested by Google AI.
Does anyone have any ideas?
For the record it's a 2020 Macbook Air with M1 chip.
I can't wait to hear from you.
