Question Is there a way to shut off only the hot water supply to the house?

Hello, Iíve been having issues with the kitchen sink, the faucet was dripping and there was a leak around the handles . I change the handles and stem, itís a two handle system, which Iíve done before but this time the hot water would not stop dripping. The water temperature to the house was 180į so I think it melted away some of the parts, I have since turned the temperature down and Iím waiting for a plumber but is there a way to shut off only the hot water to the house instead of having to shut off the entire water supply until the plumber comes . The shut off valves under the sink apparently do not work or that wouldíve been my first solution. The water comes from a pipe located in the basement which is fed to a tankless coil system, itís an oil fired burner. Keep in mind I am no expert at all . Like I said I did turn the temperature down on the thermostat but it had gotten so hot that I actually flip the switch to shut the burner off .

There should be a valve on the pipe before it goes into the water heater from the water main. Hard to see in the picture but maybe there is a valve on the pipes above to shut off flow to the heater.

We need a picture of the front of the boiler so that we can see which pipes feed the tankless coil.

Several levers

There is so many levers. There is one in the middle of the 2 pipes coming out of the boiler, there is 2 where It looks like the cold water goes to the house and possibly to the boiler and then there is one where it looks like the hot water goes to the house, that one is the only one thatís blue.

The tankless is circled in red.
The valve circled in pink is some type of tankless bypass. It may be for tempering.
The valve circled in green looks to be a shutoff.
