ALTER ROLE BYPASSRLS permission denied on Flexible Server - cannot restore attribute after accidental NOBYPASSRLS

Problem:
I accidentally ran the following command on my admin role.

Now I need to restore the BYPASSRLS attribute, but when I try to run: ALTER ROLE {name} BYPASSRLS;

I get this error: SQL Error [42501]: ERROR: permission denied to alter role Detail: Only roles with the BYPASSRLS, CREATEROLE attribute and ADMIN option on role "guerreros" may alter the BYPASSRLS attribute for this role. The issue is a chicken-and-egg situation: to grant BYPASSRLS, the executing role must already have BYPASSRLS, but "guerreros" was the only role with that attribute, and I just removed it from itself. On Flexible Server I don't have access to a real superuser, so no available role can re-grant it.

Question: How can I restore the BYPASSRLS attribute on my admin role "guerreros"? Is there a way to do this myself, or does this require a support engineer to run it with superuser privileges on the backend?
