One easy way to limit the heat going through those radiators is to bleed air into them. I've done this at my house.
You need to open the bleeder valve on those radiators you don't want to get hot, then open the drain valve on the boiler and drain out several gallons of water. This will suck air into the rads and will prevent them from getting as warm. There is still a reasonable amount of heat conduction through the piping so it is possible but not a given that they will freeze up. On my rads, the valve knobs broke off, and the all the vice grips on the stem did was sheer the stem off. Some of these puppies are just old and stubborn. -- Blue skies.
