Yes, spring-blooming iris can be cut back after the bloom.
Specifically, a well-cared iris generally does not need extensive pruning any more frequently than every three years. After the bloom, the plant needs to redirect and reprioritize life-sustaining activities into building reserves for fall and winter survival.

Deadhead the flower unless you want the seeds. Every three years, you should thin the iris or it will stop blooming.
