How can I modify an auth_token of a redis cluster if the redis engine version is below 5.0.5?

Question

I am running a redis cluster on AWS with engine version 5.0.3.

So when I tried to use this aws command to modify the auth_token

aws elasticache modify-replication-group \ --replication-group-id authtestgroup \ --auth-token This-is-the-set-token\ --auth-token-update-strategy SET \ --apply-immediately 

I got this error: An error occurred (InvalidParameterValue) when calling the ModifyReplicationGroup operation: The AUTH token modification is only supported for redis engine version 5.0.5 and above.

Is there any way I can modify the auth_token short of destroying and recreate the redis cluster?

I just want to learn if there is any known workaround to this issue.

As you pointed out, prior to Redis 5.0.5, changing the AUTH token was not supported. The only way I found to do this is to stand up a replacement cluster, which at that point you should upgrade the Redis version.
