How to make a group of cards one sided

Hi! I have a few thousand cards in a folder that I want to make them one-sided. they all have backward and forward cards which is something that I don’t want anymore. disabling it by hovering on each would take a lot of time and is not smart. I was wondering if there is an option for that ?!
I would really appreciate any help. thanks!

Open the folder, ctrl+a thrice to select all rem, then either /bpractice or ctrl+shift+b

Thank you! It worked !
