AWS Mysql unknown variable Warning Log

I upgraded AWS Aurora Mysql 5.7 to 8, but aws aurora log outputs like this. 2024-01-19T00:24:16.179185Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_authentication_kerberos_service_principal=mysql/private-write-instance.cq2fuqzvcb8i.ap-northeast-2.rds.amazonaws.com'. 2024-01-19T00:24:16.179215Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_aurora_fast_restart_caspian_enable=1'. 2024-01-19T00:24:16.179223Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_innodb_trx_commit_allow_data_loss=0'. 2024-01-19T00:24:16.179230Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_eit_enabled=1'. 2024-01-19T00:24:16.179238Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_authentication_kerberos_service_key_tab=/rdsdbdata/activedirectory/keytab'. 2024-01-19T00:24:16.179250Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_authentication_kerberos_caseins_cmp=0'. 2024-01-19T00:24:16.179258Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_aurora_fast_restart_enable=1'. 2024-01-19T00:24:16.179266Z 0 [Warning] [MY-000067] [Server] unknown variable 'loose_rpc_v2_enabled=1'.
