I'm not super familiar with this feature of mysql, but could you set the algorithm and lock for other operations when altering a table, like adding or removing an index?

for most of operations, only "In Place" algorithm takes place) https://dev.mysql.com/doc/refman/8.4/en/innodb-online-ddl-operations.html
So, I think it's not possible to set an algorithm for such kind of operations. For example, I need it only when need to modify column. And without migrations it's a bit painful :D
