How to update a specific hash in IPFS?

Hello,

I am trying to upload chunks of videos to an IPFS node. I created a folder, added the chunks, and uploaded everything to ipfs. Then, I added the folder to IPNS and could access it worldwide. The issue is whenever I update the content of the folder and re-publish to IPNS, the hash changes. Is there any way to update an specific hash of IPFS or IPNS?

Thanks!

Use ipfs key list -l to display the IPNS CIDs.

Those do not change, only what CID they point to, which happen when you do ipfs name publish --key=???
