Salesforce provides three principal organizational settings on the Account Manager Targets Setup page: distribution frequency, team member hierarchy, and default price book.

Distribution Frequency determines how target values are broken down by time period. For example, targets can be distributed into monthly, quarterly, or yearly periods depending on the configured frequency.

Team Member Hierarchy determines which users a target owner can assign targets to. Salesforce supports hierarchy models such as Manager Hierarchy, where the Manager field on User records determines reporting relationships.

The Default Price Book is used when targets are distributed by product. It automatically supplies a price book during target distribution, although an account manager can replace that selection when required.

Measures are certainly configurable for Account Manager Targets, including Revenue and custom currency or non-currency measures. However, the question specifically identifies the three main setup selections represented by Price Book, Team Member Hierarchy, and Distribution Frequency. Salesforce documents these three directly as configurable Account Manager Target setup choices.

Default Currency is not one of these Account Manager Targets setup controls.
