One way to do that is using IPNS, which you can do through your local IPFS server like this
ipfs name publish <ipfs-hash>
Once you do that, you’ll get and IPNS hash that will point to different hash every time you update it. Since Moralis has an IPFS server by default, you can access your IPNS file with
https://ipfs.moralis.io:2053/ipns/<ipns-hash>.
Keep in mind, IPNS will persist only for 24 hours so if you use such solution is by using Moralis cronjob to keep publishing every 24 hours through an API that’ll help you to keep it in IPNS.
P.S. All these are not in docs, but I know it from my own experiments.
