A thermostatic mixing valve on the system bypass could do it by returning 100% of the boiler output back to the input until the boiler came up to temp, (as previously discussed) but a HydroStat 3250 and the additional heat-well option would give you a LWCO function as well.
It looks like you get at least ~3 minutes of burn after the entering water temp hits 125F. Judging by the temperature ramp rate of the basement zone, turning the circulator off or a thermostatic mixer bypass during cold starts would cut the heat-up time on the boiler to about 1-2 minutes, which would make some of those burn cycles pretty short. Raising the high limit another 10F would get it reliably above 5 minutes per burn even with those fixes. With the smart economizers it's customary to set the high-limit to something fairly high, and let the controller manage it from there. With a heat purging controller if the boiler is already hot a call for heat from the basement might even be satisfied without the burner firing.
