How to make an account that doesnt get suggested to friends

Is there any way to make an account that doesn't get suggested to friends in any way? I am trying to make an account to make videos that are "posting until _____ happens" and part of the thing I want to do is friends not finding out. I heard that you can do it, its just that if u look into ur main account too often the account that you look at it with will be suggested and I wabt to keep using my main account like normal. Any ideas?
