Is this a valid statement about identity profile?

The statement is correct. Identity Profiles have a priority property that determines precedence when an identity is associated with accounts on more than one authoritative source. Lower numerical priority values represent higher precedence. This becomes important when several authoritative sources could potentially establish the same Identity Security Cloud identity.

SailPoint's Identity Profile REST API supports updating an existing Identity Profile through a PATCH operation. The Identity Profile data model contains the priority property, and it is not included among the properties that the Update Identity Profile endpoint prohibits from being modified. Consequently, an administrator can issue a JSON Patch operation against the /priority path to change that profile's precedence. SailPoint's published API documentation exposes both the priority field and the Identity Profile update operation.

Priority changes should be performed carefully because changing authoritative-source precedence can affect how identities are represented and which Identity Profile governs them when multiple authoritative accounts exist.

Therefore, using the REST API to modify Identity Profile priority is supported.
