There is no such parameter in 6.1, this should be for MySQL compatibility.

The parameter name is incorrect. TiDB is not MySQL. The parameter in TiDB is validate_password.mixed_case_count, and it is only available from version 6.5.

The database has already indicated that it does not recognize this parameter, meaning it is not supported.
