Perhaps. If it’s supplying a standpipe system, a single PRV is not acceptable.

I have a ESFR storage building where I am designing to a “future” water supply which is much higher than the existing water supply. The fire pump must satisfy both existing and future conditions and I thought about leaving a space for a PRV to be installed downstream of the pump discharge valve to account for the future higher pressures.
