Depending upon your water purveyors "Backflow Prevention Plan" you may be allowed to use a non-testable device. Most boiler feed valves include non-testable devices. Examples would be: The Watts 07, 7, 09 and 9 series "Dual Checks" by Watts as also available from other MFG's.
True Backflow Assemblies must be testable. But in many jurisdictions Non-testable "Dual Checks" and "Dual Checks with atmospheric relief" are acceptable.

Then that came back and wanted a testable device to certify against stagnant contamination. I wouldn't want to be the PE that said it's OK even after the fact.
