Hi, @mbeigel. Large Media doesn’t have a concept for “enabled for only this branch”. Large Media is enabled at the site level and then applies to all branches being built at Netlify. You cannot enable it for some branches and not for others.
If you want to test Large Media, I suggest creating a new repo for testing purposes because it won’t be possible to test only for a single branch.
Do you want to remove the Large Media add-on from the existing site for now? If so, please read the support guide here first:
and then let us know then you are ready.
If there are other questions about the current configuration, please let us know.
