MySQL DDL performance

Upgrading our product to support MySQL-8 we found out, that DDL queries are much slower in MySQL-8 then in MySQL-5.7
It mostly affects the installation and rollback of our application.
Rollback from the dump is 80% slower than with MySQL5.7
We do a lot of rollbacks of a database between running our test groups.
we run around 10000 queries during installation. and around half of them are DDL queries.

Is there any way to speed up DDL queries?
We already disabled binary log, but doesn't help a lot.

Thanks in advance.
