Access control for mutable file system

Hello everyone, does anyone know if access control is possible when using ipfs - mutable file system? If so are there any resources on the matter?

I would like to enable users to upload files based on variables such as NFT ownership.

Many thanks!

There is no ACL built in with IPFS.
You might checkout things like https://unlock-protocol.com/.

Peergos.org
is also implementing their solution based on IPFS.
