Have you confirmed what the temps are expected to be below the unit heater? The manufacturer’s data (or the mech engineer) may be able to provide this info.

Would it be a lesser evil if a non-ESFR 286 deg.F sprinklers having the same k factor as the ESFR sprinklers are used only near the unit heaters with the rest of the system being ESFR?
