As it was already answered in other questions, only the bucket owner (root user) can enable/disable MFA delete, using the cli.
I was not able to find an answer however on if there is a way for the bucket owner to grant permissions to other non-root users to perform permanent deletions of specific versions, using their own MFA codes, or if this is something that only the bucket owner can do.

No. MFA delete is only for the root.
