Can jus cogens norms or peremptory norms be amended internationally?

Is it possible to amend these norms, or could the international framework that supports them be modified to allow derogation or have a negative impact on them?

Yes, but you’d need to convince an international court that your case warrants it.

I was more asking if international frameworks could be changed to allow derogation in general, not on a case-by-case basis.

@Eli
Yes, that is technically possible.

You might want to dig deeper into sources on jus cogens norms to get more insight into their evolution and status.

Even a quick read of sources like Wikipedia will tell you that peremptory norms are not fully catalogued and evolve with case law and changing social norms.
