Hello there @aalexander, I hope you're having a good day so far!
There wouldn't be a way for you to remove your access from the subfolders unfortunately. The best way around this would probably be to have the owner of the folder share smaller subfolders with you individually.
Otherwise, perhaps they can share a link to the largest parent folder and then allow you editing access to subfolders when needed.
I hope this helps, let me know if you have any questions!
