XPS 9320 : LCD Failure hardware ok because working if lid is opened only after booting on a second screen

Hello, 

Following recent bios and GPU updates, my internal LCD is failing on boot if started on standalone. 

If connected to a second screen, with the lid closed until the windows boot is completed, the internal screen will work when the lid is opened. I tried to disable all lid options in the bios, tried multiple versions of GPU, but cannot come back to previous versions of bios (curently 2.24.1)

Chat GPT says that it is a know issue on this model that should be resolved with a next version of BIOS, but I don"t see anything in the support. If someone can help...
