[REQUEST] Help me for Dell 5490

I took out my wifi card in the M.2 slot of my laptop and connected a 750Tİ video card with exp gdc,

I get this message when I turn on my computer, According to the information I researched, I need to activate the multi-display option via bios, but there is no option called multi-display in my bios
i have connected egpu cables properly but i get this error while the computer is starting up,Unsupported Video Configuration Detected I get an error, (ERROR 1)
If I turn off the WLAN AND Bluetooth options via bios and turn on the computer with 750Tİ with exp gdc, I get the following error. ( ERROR 2)
