How to prevent Liquibase from executing a modified version of the changelog?

I'm running Liquibase 3.6.2 and am looking for a way to prevent developers from modifying an existing changelog by adding/removing changesets. Liquibase defines a changeset as non-mutable; changing any parameter or dependency in a changeset will throw a violation error, but unfortunately, I do not see any way to prevent this from a changelog perspective.
Essentially, I'm trying to implement a convention that once a changelog is run, it can no longer be modified. New changesets must be added to a newer changelog instead.
Is there anyway I can accomplish this? How does everyone else manage non-mutability of changelogs?

Could you please elaborate on "once a changelog is run"? There are multiple environments where changelog/changesets will be executed. Some of them do not exist yet - think about a new colleague joining your team in one month and setting up his local environment. Should changelog be open for modifications until then?

@IllyaKysil Your comment made me think a bit, and I've come to realize that you're right. In my mind, the definition is once a changelog is executed on a particular system, that it cannot be re-executed a second time. But then what prevents someone from having modified it and running the modified version on a clean DB? Nothing. So with a little more thought, it makes sense that it is based on the changesets and not the changelog. Thanks.
