While it's possible to hard-code the list of DCs used by ACS, it's not recommended, as it requires manual editing of a configuration file, which in turn requires installing a patch that allows access to the filesystem. The configuration file would have to be edited again in the future as you upgrade ACS, as it's likely to be replaced at that time.
ACS will pick a DC from the list of DCs returned when it resolves the name of the domain to which it's joined, and if/when that DC becomes unreachable it will pick another one from the list.
