Coreelec TV startup problem turned off

Good evening, I installed a VCN addon to be able to update my libraries on different Odiders in my possession in different rooms, before I used libreelec I was able via TigerVNC or Vnc-Viewer installed on a fixed pc windows remotely to control all my devices without having to turn on the TV, now they connect normally but the screen remains black provided you turn on the TV, in that case you start coreelec and the screen appears on the PC in VNC otherwise it remains as frozen waiting to receive the TV’s power on signal, it exists by chance some settings to allow them to start even with the TV off? Thank you.
