Default API method for managing Media Explorer harware outputs?

Is there any API method for managing Media Explorer harware outputs?
For example I toggle master harware output from 1/2 (monitors) to 3/4 (headphones) and I need Media Explorer harware output to follow active master harware output.

Try this function:

Code:
function MediaExplorer_SetDeviceOutput(channel, mono)
--[[
Meo-Ada Mespotine - 21st of January 2022 - licensed under MIT-license

Sets the output-channel(s) of the Media Explorer

When Media Explorer is opened, playback will be stopped and the Media Explorer will flicker for a short time. This is due limitations in Reaper.

Parameters:
  channel: set to the channel number; 1 or higher; -1, Play through first track named "Media Explorer Preview" or first selected track
  mono: true, use the mono-channel; false, use stereo-channels
--]]
  if channel>-1 then
    channel=channel-1
    if mono==true then channel=channel+1024 end
  end
  local A=reaper.GetToggleCommandState(50124)
  if A==1 then reaper.Main_OnCommand(50124, 0) end
  reaper.BR_Win32_WritePrivateProfileString("reaper_explorer", "outputidx", channel, reaper.get_ini_file())
  if A==1 then reaper.Main_OnCommand(50124, 0) end
end

MediaExplorer_SetDeviceOutput(3, false) -- this sets hardwareoutput to channel 3 in stereo
The first parameter is the channel number(1 and higher; -1 for "Play through first track named "Media Explorer Preview" or first selected track") and the second parameter sets, if mono(true) or stereo(false).

However, this will flicker an already opened MediaExplorer quickly and stop any playback. This I cannot circumvent.
But at least, you can set it now programmatically.

Reaper's own API has no such function, afaik.

Man, thnx for help.
Since I planned to change hardware outputs with closed Media Explorer, flickering will never bother me(:
