When using CMakePresets.json, what is the equivalent of remotePreGenerateCommand?

Question

I am trying to switch from CMakeSettings.json to CMakePresets.json in a Visual Studio CMake project targetting Linux.

In my current CMakeSettings.json, I used to activate a Conda environment before generating the CMake cache on remote systems (including WSL) with:

{
   ...
   "remotePreGenerateCommand": "conda activate foobar",
}

What would be the equivalent feature with CMakePresets.json? I could not find anything similar in the Visual Studio Remote Settings vendor map.
