Turning off passive hotend

[Kulitorum]

In my start gcode in Simplify3d, I set the temperature of both hotends.
I am now printing a 20 hour print that uses only hotend 0, but I cannot turn off hotend 1. Neither on the panel or by gcode.

I have send G10 P1 R0 S0 multiple times and I have tried to turn off hotend 1 on the panel.

I cannot make hotend 1 active, because it would then print part of my print with hotend1 and I cannot turn hotend off.

How can I turn off hotend 1?

Send G10 P1 S-273.

That does not work for me.

I'm sorry, I just checked and found that you need to use G10 P1 S-273 R-273.
